+	    <para>The kernel demux API defines a driver-internal interface for
+	    registering low-level, hardware specific driver to a hardware
+	    independent demux layer. It is only of interest for Digital TV
+	    device driver writers. The header file for this API is named
+	    <constant>demux.h</constant> and located in
+	    <constant>drivers/media/dvb-core</constant>.</para>
+
+	<para>The demux API should be implemented for each demux in the
+	system. It is used to select the TS source of a demux and to manage
+	the demux resources. When the demux client allocates a resource via
+	the demux API, it receives a pointer to the API of that
+	resource.</para>
+	<para>Each demux receives its TS input from a DVB front-end or from
+	memory, as set via this demux API. In a system with more than one
+	front-end, the API can be used to select one of the DVB front-ends
+	as a TS source for a demux, unless this is fixed in the HW platform.
+	The demux API only controls front-ends regarding to their connections
+	with demuxes; the APIs used to set the other front-end parameters,
+	such as tuning, are not defined in this document.</para>
+	<para>The functions that implement the abstract interface demux should
+	be defined static or module private and registered to the Demux
+	core for external access. It is not necessary to implement every
+	function in the struct <constant>dmx_demux</constant>. For example,
+	a demux interface might support Section filtering, but not PES
+	filtering. The API client is expected to check the value of any
+	function pointer before calling the function: the value of NULL means
+	that the &#8220;function is not available&#8221;.</para>
+	<para>Whenever the functions of the demux API modify shared data,
+	the possibilities of lost update and race condition problems should
+	be addressed, e.g. by protecting parts of code with mutexes.</para>
+	<para>Note that functions called from a bottom half context must not
+	sleep. Even a simple memory allocation without using GFP_ATOMIC can
+	result in a kernel thread being put to sleep if swapping is needed.
+	For example, the Linux kernel calls the functions of a network device
+	interface from a bottom half context. Thus, if a demux API function
+	is called from network device code, the function must not sleep.
+	</para>
+    </sect1>
+
+    <section id="demux_callback_api">
+	<title>Demux Callback API</title>
+	<para>This kernel-space API comprises the callback functions that
+	deliver filtered data to the demux client. Unlike the other DVB
+	kABIs, these functions are provided by the client and called from
+	the demux code.</para>
+	<para>The function pointers of this abstract interface are not
+	packed into a structure as in the other demux APIs, because the
+	callback functions are registered and used independent of each
+	other. As an example, it is possible for the API client to provide
+	several callback functions for receiving TS packets and no
+	callbacks for PES packets or sections.</para>
+	<para>The functions that implement the callback API need not be
+	re-entrant: when a demux driver calls one of these functions,
+	the driver is not allowed to call the function again before
+	the original call returns. If a callback is triggered by a
+	hardware interrupt, it is recommended to use the Linux
+	&#8220;bottom half&#8221; mechanism or start a tasklet instead of
+	making the callback function call directly from a hardware
+	interrupt.</para>
+	<para>This mechanism is implemented by
+	<link linkend='API-dmx-ts-cb'>dmx_ts_cb()</link> and
+	<link linkend='API-dmx-section-cb'>dmx_section_cb()</link>.</para>

-<section id="demux_api">
-<title>Demux API</title>
-<para>The demux API should be implemented for each demux in the system. It is used to select
-the TS source of a demux and to manage the demux resources. When the demux
-client allocates a resource via the demux API, it receives a pointer to the API of that
-resource.
-</para>
-<para>Each demux receives its TS input from a DVB front-end or from memory, as set via the
-demux API. In a system with more than one front-end, the API can be used to select one of
-the DVB front-ends as a TS source for a demux, unless this is fixed in the HW platform. The
-demux API only controls front-ends regarding their connections with demuxes; the APIs
-used to set the other front-end parameters, such as tuning, are not defined in this
-document.
-</para>
-<para>The functions that implement the abstract interface demux should be defined static or
-module private and registered to the Demux Directory for external access. It is not necessary
-to implement every function in the demux_t struct, however (for example, a demux interface
-might support Section filtering, but not TS or PES filtering). The API client is expected to
-check the value of any function pointer before calling the function: the value of NULL means
-&#8220;function not available&#8221;.
-</para>
-<para>Whenever the functions of the demux API modify shared data, the possibilities of lost
-update and race condition problems should be addressed, e.g. by protecting parts of code with
-mutexes. This is especially important on multi-processor hosts.
-</para>
-<para>Note that functions called from a bottom half context must not sleep, at least in the 2.2.x
-kernels. Even a simple memory allocation can result in a kernel thread being put to sleep if
-swapping is needed. For example, the Linux kernel calls the functions of a network device
-interface from a bottom half context. Thus, if a demux API function is called from network
-device code, the function must not sleep.

-<title>Demux Callback API</title>
-<para>This kernel-space API comprises the callback functions that deliver filtered data to the
-demux client. Unlike the other APIs, these API functions are provided by the client and called
-from the demux code.
-</para>
-<para>The function pointers of this abstract interface are not packed into a structure as in the
-other demux APIs, because the callback functions are registered and used independent
-of each other. As an example, it is possible for the API client to provide several
-callback functions for receiving TS packets and no callbacks for PES packets or
-sections.
-</para>
-<para>The functions that implement the callback API need not be re-entrant: when a demux
-driver calls one of these functions, the driver is not allowed to call the function again before
-the original call returns. If a callback is triggered by a hardware interrupt, it is recommended
-to use the Linux &#8220;bottom half&#8221; mechanism or start a tasklet instead of making the callback
-function call directly from a hardware interrupt.

+Block layer support for Persistent Reservations
+===============================================
+
+The Linux kernel supports a user space interface for simplified
+Persistent Reservations which map to block devices that support
+these (like SCSI). Persistent Reservations allow restricting
+access to block devices to specific initiators in a shared storage
+setup.
+
+This document gives a general overview of the support ioctl commands.
+For a more detailed reference please refer the the SCSI Primary
+Commands standard, specifically the section on Reservations and the
+"PERSISTENT RESERVE IN" and "PERSISTENT RESERVE OUT" commands.
+
+All implementations are expected to ensure the reservations survive
+a power loss and cover all connections in a multi path environment.
+These behaviors are optional in SPC but will be automatically applied
+by Linux.
+
+
+The following types of reservations are supported:
+--------------------------------------------------
+
+ - PR_WRITE_EXCLUSIVE
+
+	Only the initiator that owns the reservation can write to the
+	device.  Any initiator can read from the device.
+
+ - PR_EXCLUSIVE_ACCESS
+
+	Only the initiator that owns the reservation can access the
+	device.
+
+ - PR_WRITE_EXCLUSIVE_REG_ONLY
+
+	Only initiators with a registered key can write to the device,
+	Any initiator can read from the device.
+
+ - PR_EXCLUSIVE_ACCESS_REG_ONLY
+
+	Only initiators with a registered key can access the device.
+
+ - PR_WRITE_EXCLUSIVE_ALL_REGS
+
+	Only initiators with a registered key can write to the device,
+	Any initiator can read from the device.
+	All initiators with a registered key are considered reservation
+	holders.
+	Please reference the SPC spec on the meaning of a reservation
+	holder if you want to use this type. 
+
+ - PR_EXCLUSIVE_ACCESS_ALL_REGS
+
+	Only initiators with a registered key can access the device.
+	All initiators with a registered key are considered reservation
+	holders.
+	Please reference the SPC spec on the meaning of a reservation
+	holder if you want to use this type. 
+
+
+The following ioctl are supported:
+----------------------------------
+
+1. IOC_PR_REGISTER
+
+This ioctl command registers a new reservation if the new_key argument
+is non-null.  If no existing reservation exists old_key must be zero,
+if an existing reservation should be replaced old_key must contain
+the old reservation key.
+
+If the new_key argument is 0 it unregisters the existing reservation passed
+in old_key.
+
+
+2. IOC_PR_RESERVE
+
+This ioctl command reserves the device and thus restricts access for other
+devices based on the type argument.  The key argument must be the existing
+reservation key for the device as acquired by the IOC_PR_REGISTER,
+IOC_PR_REGISTER_IGNORE, IOC_PR_PREEMPT or IOC_PR_PREEMPT_ABORT commands.
+
+
+3. IOC_PR_RELEASE
+
+This ioctl command releases the reservation specified by key and flags
+and thus removes any access restriction implied by it.
+
+
+4. IOC_PR_PREEMPT
+
+This ioctl command releases the existing reservation referred to by
+old_key and replaces it with a a new reservation of type for the
+reservation key new_key.
+
+
+5. IOC_PR_PREEMPT_ABORT
+
+This ioctl command works like IOC_PR_PREEMPT except that it also aborts
+any outstanding command sent over a connection identified by old_key.
+
+6. IOC_PR_CLEAR
+
+This ioctl command unregisters both key and any other reservation key
+registered with the device and drops any existing reservation.
+
+
+Flags
+-----
+
+All the ioctls have a flag field.  Currently only one flag is supported:
+
+ - PR_FL_IGNORE_KEY
+
+	Ignore the existing reservation key.  This is commonly supported for
+	IOC_PR_REGISTER, and some implementation may support the flag for
+	IOC_PR_RESERVE.
+
+For all unknown flags the kernel will return -EOPNOTSUPP.

+There are several ways to configure and manage zram device(-s):

+=======
+For the sake of simplicity we skip error checking parts in most of the

+The CPRMAN clock controller generates clocks in the audio power domain

+oscillator, a level of PLL dividers that produce channels off of the
+few PLLs, and a level of mostly-generic clock generators sourcing from

 ----------------------------------
 
@@ -118,6 +131,30 @@ Every GPIO controller node must contain both an empty "gpio-controller"
 property, and a #gpio-cells integer property, which indicates the number of
 cells in a gpio-specifier.
 
+Optionally, a GPIO controller may have a "ngpios" property. This property
+indicates the number of in-use slots of available slots for GPIOs. The
+typical example is something like this: the hardware register is 32 bits
+wide, but only 18 of the bits have a physical counterpart. The driver is
+generally written so that all 32 bits can be used, but the IP block is reused
+in a lot of designs, some using all 32 bits, some using 18 and some using
+12. In this case, setting "ngpios = <18>;" informs the driver that only the
+first 18 GPIOs, at local offset 0 .. 17, are in use.
+
+If these GPIOs do not happen to be the first N GPIOs at offset 0...N-1, an
+additional bitmask is needed to specify which GPIOs are actually in use,
+and which are dummies. The bindings for this case has not yet been
+specified, but should be specified if/when such hardware appears.
+
+Example:
+
+gpio-controller@00000000 {

+	reg = <0x00000000 0x1000>;
+	gpio-controller;
+	#gpio-cells = <2>;

 The GPIO chip may contain GPIO hog definitions. GPIO hogging is a mechanism
 providing automatic GPIO request and configuration as part of the

+Optional properties:
+
+  - dlg,disable-key-power : Disable power-down using a long key-press. If this

+controller and an USART. Only one function can be used at a time and is chosen
+at boot time according to the device tree.
+
+Required properties:
+- compatible:		Should be "atmel,sama5d2-flexcom"
+- reg:			Should be the offset/length value for Flexcom dedicated
+			I/O registers (without USART, TWI or SPI registers).
+- clocks:		Should be the Flexcom peripheral clock from PMC.
+- #address-cells:	Should be <1>
+- #size-cells:		Should be <1>
+- ranges:		Should be one range for the full I/O register region
+			(including USART, TWI and SPI registers).
+- atmel,flexcom-mode:	Should be one of the following values:
+			- <1> for USART
+			- <2> for SPI
+			- <3> for I2C
+
+Required child:
+A single available child device of type matching the "atmel,flexcom-mode"
+property.
+
+The phandle provided by the clocks property of the child is the same as one for
+the Flexcom parent.
+
+For other properties, please refer to the documentations of the respective

+Freescale's NAND flash controller (NFC)
+
+This variant of the Freescale NAND flash controller (NFC) can be found on
+Vybrid (vf610), MPC5125, MCF54418 and Kinetis K70.
+
+Required properties:
+- compatible: Should be set to "fsl,vf610-nfc".
+- reg: address range of the NFC.
+- interrupts: interrupt of the NFC.
+- #address-cells: shall be set to 1. Encode the nand CS.
+- #size-cells : shall be set to 0.
+- assigned-clocks: main clock from the SoC, for Vybrid <&clks VF610_CLK_NFC>;
+- assigned-clock-rates: The NAND bus timing is derived from this clock
+    rate and should not exceed maximum timing for any NAND memory chip
+    in a board stuffing. Typical NAND memory timings derived from this
+    clock are found in the SoC hardware reference manual. Furthermore,
+    there might be restrictions on maximum rates when using hardware ECC.
+
+- #address-cells, #size-cells : Must be present if the device has sub-nodes
+  representing partitions.
+
+Required children nodes:
+Children nodes represent the available nand chips. Currently the driver can
+only handle one NAND chip.

+Required properties:
+- compatible: Should be set to "fsl,vf610-nfc-cs".
+- nand-bus-width: see nand.txt
+- nand-ecc-mode: see nand.txt

+- ae-name: accelerator name who provides this interface,
+  is simply a name referring to the name of name in the accelerator node.
+- port-id: is the index of port provided by DSAF (the accelerator). DSAF can
+  connect to 8 PHYs. Port 0 to 1 are both used for adminstration purpose. They
+  are called debug ports.
+
+  The remaining 6 PHYs are taken according to the mode of DSAF.
+
+  In NIC mode of DSAF, all 6 PHYs are taken as ethernet ports to the CPU. The
+  port-id can be 2 to 7. Here is the diagram:
+            +-----+---------------+

+
+  In Switch mode of DSAF, all 6 PHYs are taken as physical ports connect to a
+  LAN Switch while the CPU side assume itself have one single NIC connect to
+  this switch. In this case, the port-id will be 2 only.

+This document describes the generic device tree binding for describing the
+relationship between PCI devices and MSI controllers.
+
+Each PCI device under a root complex is uniquely identified by its Requester ID
+(AKA RID). A Requester ID is a triplet of a Bus number, Device number, and
+Function number.
+
+For the purpose of this document, when treated as a numeric value, a RID is
+formatted such that:
+
+* Bits [15:8] are the Bus number.
+* Bits [7:3] are the Device number.
+* Bits [2:0] are the Function number.
+* Any other bits required for padding must be zero.
+
+MSIs may be distinguished in part through the use of sideband data accompanying
+writes. In the case of PCI devices, this sideband data may be derived from the
+Requester ID. A mechanism is required to associate a device with both the MSI
+controllers it can address, and the sideband data that will be associated with
+its writes to those controllers.
+
+For generic MSI bindings, see
+Documentation/devicetree/bindings/interrupt-controller/msi.txt.
+
+
+PCI root complex
+================
+
+Optional properties
+-------------------
+
+- msi-map: Maps a Requester ID to an MSI controller and associated
+  msi-specifier data. The property is an arbitrary number of tuples of
+  (rid-base,msi-controller,msi-base,length), where:
+
+  * rid-base is a single cell describing the first RID matched by the entry.
+
+  * msi-controller is a single phandle to an MSI controller
+
+  * msi-base is an msi-specifier describing the msi-specifier produced for the
+    first RID matched by the entry.
+
+  * length is a single cell describing how many consecutive RIDs are matched
+    following the rid-base.
+
+  Any RID r in the interval [rid-base, rid-base + length) is associated with
+  the listed msi-controller, with the msi-specifier (r - rid-base + msi-base).
+
+- msi-map-mask: A mask to be applied to each Requester ID prior to being mapped
+  to an msi-specifier per the msi-map property.
+
+- msi-parent: Describes the MSI parent of the root complex itself. Where
+  the root complex and MSI controller do not pass sideband data with MSI
+  writes, this property may be used to describe the MSI controller(s)
+  used by PCI devices under the root complex, if defined as such in the
+  binding for the root complex.
+

+- <https://lwn.net/Articles/649729/> RCU-walk: faster pathname lookup in Linux
+- <https://lwn.net/Articles/650786/> A walk among the symlinks
+
+Written by Neil Brown with help from Al Viro and Jon Corbet.
+
+Introduction
+------------
+
+The most obvious aspect of pathname lookup, which very little
+exploration is needed to discover, is that it is complex.  There are
+many rules, special cases, and implementation alternatives that all
+combine to confuse the unwary reader.  Computer science has long been
+acquainted with such complexity and has tools to help manage it.  One
+tool that we will make extensive use of is "divide and conquer".  For
+the early parts of the analysis we will divide off symlinks - leaving
+them until the final part.  Well before we get to symlinks we have
+another major division based on the VFS's approach to locking which
+will allow us to review "REF-walk" and "RCU-walk" separately.  But we
+are getting ahead of ourselves.  There are some important low level
+distinctions we need to clarify first.
+
+There are two sorts of ...
+--------------------------
+
+[`openat()`]: http://man7.org/linux/man-pages/man2/openat.2.html
+
+Pathnames (sometimes "file names"), used to identify objects in the
+filesystem, will be familiar to most readers.  They contain two sorts
+of elements: "slashes" that are sequences of one or more "`/`"
+characters, and "components" that are sequences of one or more
+non-"`/`" characters.  These form two kinds of paths.  Those that
+start with slashes are "absolute" and start from the filesystem root.
+The others are "relative" and start from the current directory, or
+from some other location specified by a file descriptor given to a
+"xxx`at`" system call such as "[`openat()`]".
+
+[`execveat()`]: http://man7.org/linux/man-pages/man2/execveat.2.html
+
+It is tempting to describe the second kind as starting with a
+component, but that isn't always accurate: a pathname can lack both
+slashes and components, it can be empty, in other words.  This is
+generally forbidden in POSIX, but some of those "xxx`at`" system calls
+in Linux permit it when the `AT_EMPTY_PATH` flag is given.  For
+example, if you have an open file descriptor on an executable file you
+can execute it by calling [`execveat()`] passing the file descriptor,
+an empty path, and the `AT_EMPTY_PATH` flag.
+
+These paths can be divided into two sections: the final component and
+everything else.  The "everything else" is the easy bit.  In all cases
+it must identify a directory that already exists, otherwise an error
+such as `ENOENT` or `ENOTDIR` will be reported.
+
+The final component is not so simple.  Not only do different system
+calls interpret it quite differently (e.g. some create it, some do
+not), but it might not even exist: neither the empty pathname nor the
+pathname that is just slashes have a final component.  If it does
+exist, it could be "`.`" or "`..`" which are handled quite differently
+from other components.
+
+[POSIX]: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_12
+
+If a pathname ends with a slash, such as "`/tmp/foo/`" it might be
+tempting to consider that to have an empty final component.  In many
+ways that would lead to correct results, but not always.  In
+particular, `mkdir()` and `rmdir()` each create or remove a directory named
+by the final component, and they are required to work with pathnames
+ending in "`/`".  According to [POSIX]
+
+> A pathname that contains at least one non- &lt;slash> character and
+> that ends with one or more trailing &lt;slash> characters shall not
+> be resolved successfully unless the last pathname component before
+> the trailing <slash> characters names an existing directory or a
+> directory entry that is to be created for a directory immediately
+> after the pathname is resolved.
+
+The Linux pathname walking code (mostly in `fs/namei.c`) deals with
+all of these issues: breaking the path into components, handling the
+"everything else" quite separately from the final component, and
+checking that the trailing slash is not used where it isn't
+permitted.  It also addresses the important issue of concurrent
+access.
+
+While one process is looking up a pathname, another might be making
+changes that affect that lookup.  One fairly extreme case is that if
+"a/b" were renamed to "a/c/b" while another process were looking up
+"a/b/..", that process might successfully resolve on "a/c".
+Most races are much more subtle, and a big part of the task of
+pathname lookup is to prevent them from having damaging effects.  Many
+of the possible races are seen most clearly in the context of the
+"dcache" and an understanding of that is central to understanding
+pathname lookup.
+
+More than just a cache.
+-----------------------
+
+The "dcache" caches information about names in each filesystem to
+make them quickly available for lookup.  Each entry (known as a
+"dentry") contains three significant fields: a component name, a
+pointer to a parent dentry, and a pointer to the "inode" which
+contains further information about the object in that parent with
+the given name.  The inode pointer can be `NULL` indicating that the
+name doesn't exist in the parent.  While there can be linkage in the
+dentry of a directory to the dentries of the children, that linkage is
+not used for pathname lookup, and so will not be considered here.
+
+The dcache has a number of uses apart from accelerating lookup.  One
+that will be particularly relevant is that it is closely integrated
+with the mount table that records which filesystem is mounted where.
+What the mount table actually stores is which dentry is mounted on top
+of which other dentry.
+
+When considering the dcache, we have another of our "two types"
+distinctions: there are two types of filesystems.
+
+Some filesystems ensure that the information in the dcache is always
+completely accurate (though not necessarily complete).  This can allow
+the VFS to determine if a particular file does or doesn't exist
+without checking with the filesystem, and means that the VFS can
+protect the filesystem against certain races and other problems.
+These are typically "local" filesystems such as ext3, XFS, and Btrfs.
+
+Other filesystems don't provide that guarantee because they cannot.
+These are typically filesystems that are shared across a network,
+whether remote filesystems like NFS and 9P, or cluster filesystems
+like ocfs2 or cephfs.  These filesystems allow the VFS to revalidate
+cached information, and must provide their own protection against
+awkward races.  The VFS can detect these filesystems by the
+`DCACHE_OP_REVALIDATE` flag being set in the dentry.
+
+REF-walk: simple concurrency management with refcounts and spinlocks
+--------------------------------------------------------------------
+
+With all of those divisions carefully classified, we can now start
+looking at the actual process of walking along a path.  In particular
+we will start with the handling of the "everything else" part of a
+pathname, and focus on the "REF-walk" approach to concurrency
+management.  This code is found in the `link_path_walk()` function, if
+you ignore all the places that only run when "`LOOKUP_RCU`"
+(indicating the use of RCU-walk) is set.
+
+[Meet the Lockers]: https://lwn.net/Articles/453685/
+
+REF-walk is fairly heavy-handed with locks and reference counts.  Not
+as heavy-handed as in the old "big kernel lock" days, but certainly not
+afraid of taking a lock when one is needed.  It uses a variety of
+different concurrency controls.  A background understanding of the
+various primitives is assumed, or can be gleaned from elsewhere such
+as in [Meet the Lockers].
+
+The locking mechanisms used by REF-walk include:
+
+### dentry->d_lockref ###
+
+This uses the lockref primitive to provide both a spinlock and a
+reference count.  The special-sauce of this primitive is that the
+conceptual sequence "lock; inc_ref; unlock;" can often be performed
+with a single atomic memory operation.
+
+Holding a reference on a dentry ensures that the dentry won't suddenly
+be freed and used for something else, so the values in various fields
+will behave as expected.  It also protects the `->d_inode` reference
+to the inode to some extent.
+
+The association between a dentry and its inode is fairly permanent.
+For example, when a file is renamed, the dentry and inode move
+together to the new location.  When a file is created the dentry will
+initially be negative (i.e. `d_inode` is `NULL`), and will be assigned
+to the new inode as part of the act of creation.
+
+When a file is deleted, this can be reflected in the cache either by
+setting `d_inode` to `NULL`, or by removing it from the hash table
+(described shortly) used to look up the name in the parent directory.
+If the dentry is still in use the second option is used as it is
+perfectly legal to keep using an open file after it has been deleted
+and having the dentry around helps.  If the dentry is not otherwise in
+use (i.e. if the refcount in `d_lockref` is one), only then will
+`d_inode` be set to `NULL`.  Doing it this way is more efficient for a
+very common case.
+
+So as long as a counted reference is held to a dentry, a non-`NULL` `->d_inode`
+value will never be changed.
+
+### dentry->d_lock ###
+
+`d_lock` is a synonym for the spinlock that is part of `d_lockref` above.
+For our purposes, holding this lock protects against the dentry being
+renamed or unlinked.  In particular, its parent (`d_parent`), and its
+name (`d_name`) cannot be changed, and it cannot be removed from the
+dentry hash table.
+
+When looking for a name in a directory, REF-walk takes `d_lock` on
+each candidate dentry that it finds in the hash table and then checks
+that the parent and name are correct.  So it doesn't lock the parent
+while searching in the cache; it only locks children.
+
+When looking for the parent for a given name (to handle "`..`"),
+REF-walk can take `d_lock` to get a stable reference to `d_parent`,
+but it first tries a more lightweight approach.  As seen in
+`dget_parent()`, if a reference can be claimed on the parent, and if
+subsequently `d_parent` can be seen to have not changed, then there is
+no need to actually take the lock on the child.
+
+### rename_lock ###
+
+Looking up a given name in a given directory involves computing a hash
+from the two values (the name and the dentry of the directory),
+accessing that slot in a hash table, and searching the linked list
+that is found there.
+
+When a dentry is renamed, the name and the parent dentry can both
+change so the hash will almost certainly change too.  This would move the
+dentry to a different chain in the hash table.  If a filename search
+happened to be looking at a dentry that was moved in this way,
+it might end up continuing the search down the wrong chain,
+and so miss out on part of the correct chain.
+
+The name-lookup process (`d_lookup()`) does _not_ try to prevent this
+from happening, but only to detect when it happens.
+`rename_lock` is a seqlock that is updated whenever any dentry is
+renamed.  If `d_lookup` finds that a rename happened while it
+unsuccessfully scanned a chain in the hash table, it simply tries
+again.
+
+### inode->i_mutex ###
+
+`i_mutex` is a mutex that serializes all changes to a particular
+directory.  This ensures that, for example, an `unlink()` and a `rename()`
+cannot both happen at the same time.  It also keeps the directory
+stable while the filesystem is asked to look up a name that is not
+currently in the dcache.
+
+This has a complementary role to that of `d_lock`: `i_mutex` on a
+directory protects all of the names in that directory, while `d_lock`
+on a name protects just one name in a directory.  Most changes to the
+dcache hold `i_mutex` on the relevant directory inode and briefly take
+`d_lock` on one or more the dentries while the change happens.  One
+exception is when idle dentries are removed from the dcache due to
+memory pressure.  This uses `d_lock`, but `i_mutex` plays no role.
+
+The mutex affects pathname lookup in two distinct ways.  Firstly it
+serializes lookup of a name in a directory.  `walk_component()` uses
+`lookup_fast()` first which, in turn, checks to see if the name is in the cache,
+using only `d_lock` locking.  If the name isn't found, then `walk_component()`
+falls back to `lookup_slow()` which takes `i_mutex`, checks again that
+the name isn't in the cache, and then calls in to the filesystem to get a
+definitive answer.  A new dentry will be added to the cache regardless of
+the result.
+
+Secondly, when pathname lookup reaches the final component, it will
+sometimes need to take `i_mutex` before performing the last lookup so
+that the required exclusion can be achieved.  How path lookup chooses
+to take, or not take, `i_mutex` is one of the
+issues addressed in a subsequent section.
+
+### mnt->mnt_count ###
+
+`mnt_count` is a per-CPU reference counter on "`mount`" structures.
+Per-CPU here means that incrementing the count is cheap as it only
+uses CPU-local memory, but checking if the count is zero is expensive as
+it needs to check with every CPU.  Taking a `mnt_count` reference
+prevents the mount structure from disappearing as the result of regular
+unmount operations, but does not prevent a "lazy" unmount.  So holding
+`mnt_count` doesn't ensure that the mount remains in the namespace and,
+in particular, doesn't stabilize the link to the mounted-on dentry.  It
+does, however, ensure that the `mount` data structure remains coherent,
+and it provides a reference to the root dentry of the mounted
+filesystem.  So a reference through `->mnt_count` provides a stable
+reference to the mounted dentry, but not the mounted-on dentry.
+
+### mount_lock ###
+
+`mount_lock` is a global seqlock, a bit like `rename_lock`.  It can be used to
+check if any change has been made to any mount points.
+
+While walking down the tree (away from the root) this lock is used when
+crossing a mount point to check that the crossing was safe.  That is,
+the value in the seqlock is read, then the code finds the mount that
+is mounted on the current directory, if there is one, and increments
+the `mnt_count`.  Finally the value in `mount_lock` is checked against
+the old value.  If there is no change, then the crossing was safe.  If there
+was a change, the `mnt_count` is decremented and the whole process is
+retried.
+
+When walking up the tree (towards the root) by following a ".." link,
+a little more care is needed.  In this case the seqlock (which
+contains both a counter and a spinlock) is fully locked to prevent
+any changes to any mount points while stepping up.  This locking is
+needed to stabilize the link to the mounted-on dentry, which the
+refcount on the mount itself doesn't ensure.
+
+### RCU ###
+
+Finally the global (but extremely lightweight) RCU read lock is held
+from time to time to ensure certain data structures don't get freed
+unexpectedly.
+
+In particular it is held while scanning chains in the dcache hash
+table, and the mount point hash table.
+
+Bringing it together with `struct nameidata`
+--------------------------------------------
+
+[First edition Unix]: http://minnie.tuhs.org/cgi-bin/utree.pl?file=V1/u2.s
+
+Throughout the process of walking a path, the current status is stored
+in a `struct nameidata`, "namei" being the traditional name - dating
+all the way back to [First Edition Unix] - of the function that
+converts a "name" to an "inode".  `struct nameidata` contains (among
+other fields):
+
+### `struct path path` ###
+
+A `path` contains a `struct vfsmount` (which is
+embedded in a `struct mount`) and a `struct dentry`.  Together these
+record the current status of the walk.  They start out referring to the
+starting point (the current working directory, the root directory, or some other
+directory identified by a file descriptor), and are updated on each
+step.  A reference through `d_lockref` and `mnt_count` is always
+held.
+
+### `struct qstr last` ###
+
+This is a string together with a length (i.e. _not_ `nul` terminated)
+that is the "next" component in the pathname.
+
+### `int last_type` ###
+
+This is one of `LAST_NORM`, `LAST_ROOT`, `LAST_DOT`, `LAST_DOTDOT`, or
+`LAST_BIND`.  The `last` field is only valid if the type is
+`LAST_NORM`.  `LAST_BIND` is used when following a symlink and no
+components of the symlink have been processed yet.  Others should be
+fairly self-explanatory.
+
+### `struct path root` ###
+
+This is used to hold a reference to the effective root of the
+filesystem.  Often that reference won't be needed, so this field is
+only assigned the first time it is used, or when a non-standard root
+is requested.  Keeping a reference in the `nameidata` ensures that
+only one root is in effect for the entire path walk, even if it races
+with a `chroot()` system call.
+
+The root is needed when either of two conditions holds: (1) either the
+pathname or a symbolic link starts with a "'/'", or (2) a "`..`"
+component is being handled, since "`..`" from the root must always stay
+at the root.  The value used is usually the current root directory of
+the calling process.  An alternate root can be provided as when
+`sysctl()` calls `file_open_root()`, and when NFSv4 or Btrfs call
+`mount_subtree()`.  In each case a pathname is being looked up in a very
+specific part of the filesystem, and the lookup must not be allowed to
+escape that subtree.  It works a bit like a local `chroot()`.
+
+Ignoring the handling of symbolic links, we can now describe the
+"`link_path_walk()`" function, which handles the lookup of everything
+except the final component as:
+
+>  Given a path (`name`) and a nameidata structure (`nd`), check that the
+>  current directory has execute permission and then advance `name`
+>  over one component while updating `last_type` and `last`.  If that
+>  was the final component, then return, otherwise call
+>  `walk_component()` and repeat from the top.
+
+`walk_component()` is even easier.  If the component is `LAST_DOTS`,
+it calls `handle_dots()` which does the necessary locking as already
+described.  If it finds a `LAST_NORM` component it first calls
+"`lookup_fast()`" which only looks in the dcache, but will ask the
+filesystem to revalidate the result if it is that sort of filesystem.
+If that doesn't get a good result, it calls "`lookup_slow()`" which
+takes the `i_mutex`, rechecks the cache, and then asks the filesystem
+to find a definitive answer.  Each of these will call
+`follow_managed()` (as described below) to handle any mount points.
+
+In the absence of symbolic links, `walk_component()` creates a new
+`struct path` containing a counted reference to the new dentry and a
+reference to the new `vfsmount` which is only counted if it is
+different from the previous `vfsmount`.  It then calls
+`path_to_nameidata()` to install the new `struct path` in the
+`struct nameidata` and drop the unneeded references.
+
+This "hand-over-hand" sequencing of getting a reference to the new
+dentry before dropping the reference to the previous dentry may
+seem obvious, but is worth pointing out so that we will recognize its
+analogue in the "RCU-walk" version.
+
+Handling the final component.
+-----------------------------
+
+`link_path_walk()` only walks as far as setting `nd->last` and
+`nd->last_type` to refer to the final component of the path.  It does
+not call `walk_component()` that last time.  Handling that final
+component remains for the caller to sort out. Those callers are
+`path_lookupat()`, `path_parentat()`, `path_mountpoint()` and
+`path_openat()` each of which handles the differing requirements of
+different system calls.
+
+`path_parentat()` is clearly the simplest - it just wraps a little bit
+of housekeeping around `link_path_walk()` and returns the parent
+directory and final component to the caller.  The caller will be either
+aiming to create a name (via `filename_create()`) or remove or rename
+a name (in which case `user_path_parent()` is used).  They will use
+`i_mutex` to exclude other changes while they validate and then
+perform their operation.
+
+`path_lookupat()` is nearly as simple - it is used when an existing
+object is wanted such as by `stat()` or `chmod()`.  It essentially just
+calls `walk_component()` on the final component through a call to
+`lookup_last()`.  `path_lookupat()` returns just the final dentry.
+
+`path_mountpoint()` handles the special case of unmounting which must
+not try to revalidate the mounted filesystem.  It effectively
+contains, through a call to `mountpoint_last()`, an alternate
+implementation of `lookup_slow()` which skips that step.  This is
+important when unmounting a filesystem that is inaccessible, such as
+one provided by a dead NFS server.
+
+Finally `path_openat()` is used for the `open()` system call; it
+contains, in support functions starting with "`do_last()`", all the
+complexity needed to handle the different subtleties of O_CREAT (with
+or without O_EXCL), final "`/`" characters, and trailing symbolic
+links.  We will revisit this in the final part of this series, which
+focuses on those symbolic links.  "`do_last()`" will sometimes, but
+not always, take `i_mutex`, depending on what it finds.
+
+Each of these, or the functions which call them, need to be alert to
+the possibility that the final component is not `LAST_NORM`.  If the
+goal of the lookup is to create something, then any value for
+`last_type` other than `LAST_NORM` will result in an error.  For
+example if `path_parentat()` reports `LAST_DOTDOT`, then the caller
+won't try to create that name.  They also check for trailing slashes
+by testing `last.name[last.len]`.  If there is any character beyond
+the final component, it must be a trailing slash.
+
+Revalidation and automounts
+---------------------------
+
+Apart from symbolic links, there are only two parts of the "REF-walk"
+process not yet covered.  One is the handling of stale cache entries
+and the other is automounts.
+
+On filesystems that require it, the lookup routines will call the
+`->d_revalidate()` dentry method to ensure that the cached information
+is current.  This will often confirm validity or update a few details
+from a server.  In some cases it may find that there has been change
+further up the path and that something that was thought to be valid
+previously isn't really.  When this happens the lookup of the whole
+path is aborted and retried with the "`LOOKUP_REVAL`" flag set.  This
+forces revalidation to be more thorough.  We will see more details of
+this retry process in the next article.
+
+Automount points are locations in the filesystem where an attempt to
+lookup a name can trigger changes to how that lookup should be
+handled, in particular by mounting a filesystem there.  These are
+covered in greater detail in autofs4.txt in the Linux documentation
+tree, but a few notes specifically related to path lookup are in order
+here.
+
+The Linux VFS has a concept of "managed" dentries which is reflected
+in function names such as "`follow_managed()`".  There are three
+potentially interesting things about these dentries corresponding
+to three different flags that might be set in `dentry->d_flags`:
+
+### `DCACHE_MANAGE_TRANSIT` ###
+
+If this flag has been set, then the filesystem has requested that the
+`d_manage()` dentry operation be called before handling any possible
+mount point.  This can perform two particular services:
+
+It can block to avoid races.  If an automount point is being
+unmounted, the `d_manage()` function will usually wait for that
+process to complete before letting the new lookup proceed and possibly
+trigger a new automount.
+
+It can selectively allow only some processes to transit through a
+mount point.  When a server process is managing automounts, it may
+need to access a directory without triggering normal automount
+processing.  That server process can identify itself to the `autofs`
+filesystem, which will then give it a special pass through
+`d_manage()` by returning `-EISDIR`.
+
+### `DCACHE_MOUNTED` ###
+
+This flag is set on every dentry that is mounted on.  As Linux
+supports multiple filesystem namespaces, it is possible that the
+dentry may not be mounted on in *this* namespace, just in some
+other.  So this flag is seen as a hint, not a promise.
+
+If this flag is set, and `d_manage()` didn't return `-EISDIR`,
+`lookup_mnt()` is called to examine the mount hash table (honoring the
+`mount_lock` described earlier) and possibly return a new `vfsmount`
+and a new `dentry` (both with counted references).
+
+### `DCACHE_NEED_AUTOMOUNT` ###
+
+If `d_manage()` allowed us to get this far, and `lookup_mnt()` didn't
+find a mount point, then this flag causes the `d_automount()` dentry
+operation to be called.
+
+The `d_automount()` operation can be arbitrarily complex and may
+communicate with server processes etc. but it should ultimately either
+report that there was an error, that there was nothing to mount, or
+should provide an updated `struct path` with new `dentry` and `vfsmount`.
+
+In the latter case, `finish_automount()` will be called to safely
+install the new mount point into the mount table.
+
+There is no new locking of import here and it is important that no
+locks (only counted references) are held over this processing due to
+the very real possibility of extended delays.
+This will become more important next time when we examine RCU-walk
+which is particularly sensitive to delays.
+
+RCU-walk - faster pathname lookup in Linux
+==========================================
+
+RCU-walk is another algorithm for performing pathname lookup in Linux.
+It is in many ways similar to REF-walk and the two share quite a bit
+of code.  The significant difference in RCU-walk is how it allows for
+the possibility of concurrent access.
+
+We noted that REF-walk is complex because there are numerous details
+and special cases.  RCU-walk reduces this complexity by simply
+refusing to handle a number of cases -- it instead falls back to
+REF-walk.  The difficulty with RCU-walk comes from a different
+direction: unfamiliarity.  The locking rules when depending on RCU are
+quite different from traditional locking, so we will spend a little extra
+time when we come to those.
+
+Clear demarcation of roles
+--------------------------
+
+The easiest way to manage concurrency is to forcibly stop any other
+thread from changing the data structures that a given thread is
+looking at.  In cases where no other thread would even think of
+changing the data and lots of different threads want to read at the
+same time, this can be very costly.  Even when using locks that permit
+multiple concurrent readers, the simple act of updating the count of
+the number of current readers can impose an unwanted cost.  So the
+goal when reading a shared data structure that no other process is
+changing is to avoid writing anything to memory at all.  Take no
+locks, increment no counts, leave no footprints.
+
+The REF-walk mechanism already described certainly doesn't follow this
+principle, but then it is really designed to work when there may well
+be other threads modifying the data.  RCU-walk, in contrast, is
+designed for the common situation where there are lots of frequent
+readers and only occasional writers.  This may not be common in all
+parts of the filesystem tree, but in many parts it will be.  For the
+other parts it is important that RCU-walk can quickly fall back to
+using REF-walk.
+
+Pathname lookup always starts in RCU-walk mode but only remains there
+as long as what it is looking for is in the cache and is stable.  It
+dances lightly down the cached filesystem image, leaving no footprints
+and carefully watching where it is, to be sure it doesn't trip.  If it
+notices that something has changed or is changing, or if something
+isn't in the cache, then it tries to stop gracefully and switch to
+REF-walk.
+
+This stopping requires getting a counted reference on the current
+`vfsmount` and `dentry`, and ensuring that these are still valid -
+that a path walk with REF-walk would have found the same entries.
+This is an invariant that RCU-walk must guarantee.  It can only make
+decisions, such as selecting the next step, that are decisions which
+REF-walk could also have made if it were walking down the tree at the
+same time.  If the graceful stop succeeds, the rest of the path is
+processed with the reliable, if slightly sluggish, REF-walk.  If
+RCU-walk finds it cannot stop gracefully, it simply gives up and
+restarts from the top with REF-walk.
+
+This pattern of "try RCU-walk, if that fails try REF-walk" can be
+clearly seen in functions like `filename_lookup()`,
+`filename_parentat()`, `filename_mountpoint()`,
+`do_filp_open()`, and `do_file_open_root()`.  These five
+correspond roughly to the four `path_`* functions we met earlier,
+each of which calls `link_path_walk()`.  The `path_*` functions are
+called using different mode flags until a mode is found which works.
+They are first called with `LOOKUP_RCU` set to request "RCU-walk".  If
+that fails with the error `ECHILD` they are called again with no
+special flag to request "REF-walk".  If either of those report the
+error `ESTALE` a final attempt is made with `LOOKUP_REVAL` set (and no
+`LOOKUP_RCU`) to ensure that entries found in the cache are forcibly
+revalidated - normally entries are only revalidated if the filesystem
+determines that they are too old to trust.
+
+The `LOOKUP_RCU` attempt may drop that flag internally and switch to
+REF-walk, but will never then try to switch back to RCU-walk.  Places
+that trip up RCU-walk are much more likely to be near the leaves and
+so it is very unlikely that there will be much, if any, benefit from
+switching back.
+
+RCU and seqlocks: fast and light
+--------------------------------
+
+RCU is, unsurprisingly, critical to RCU-walk mode.  The
+`rcu_read_lock()` is held for the entire time that RCU-walk is walking
+down a path.  The particular guarantee it provides is that the key
+data structures - dentries, inodes, super_blocks, and mounts - will
+not be freed while the lock is held.  They might be unlinked or
+invalidated in one way or another, but the memory will not be
+repurposed so values in various fields will still be meaningful.  This
+is the only guarantee that RCU provides; everything else is done using
+seqlocks.
+
+As we saw above, REF-walk holds a counted reference to the current
+dentry and the current vfsmount, and does not release those references
+before taking references to the "next" dentry or vfsmount.  It also
+sometimes takes the `d_lock` spinlock.  These references and locks are
+taken to prevent certain changes from happening.  RCU-walk must not
+take those references or locks and so cannot prevent such changes.
+Instead, it checks to see if a change has been made, and aborts or
+retries if it has.
+
+To preserve the invariant mentioned above (that RCU-walk may only make
+decisions that REF-walk could have made), it must make the checks at
+or near the same places that REF-walk holds the references.  So, when
+REF-walk increments a reference count or takes a spinlock, RCU-walk
+samples the status of a seqlock using `read_seqcount_begin()` or a
+similar function.  When REF-walk decrements the count or drops the
+lock, RCU-walk checks if the sampled status is still valid using
+`read_seqcount_retry()` or similar.
+
+However, there is a little bit more to seqlocks than that.  If
+RCU-walk accesses two different fields in a seqlock-protected
+structure, or accesses the same field twice, there is no a priori
+guarantee of any consistency between those accesses.  When consistency
+is needed - which it usually is - RCU-walk must take a copy and then
+use `read_seqcount_retry()` to validate that copy.
+
+`read_seqcount_retry()` not only checks the sequence number, but also
+imposes a memory barrier so that no memory-read instruction from
+*before* the call can be delayed until *after* the call, either by the
+CPU or by the compiler.  A simple example of this can be seen in
+`slow_dentry_cmp()` which, for filesystems which do not use simple
+byte-wise name equality, calls into the filesystem to compare a name
+against a dentry.  The length and name pointer are copied into local
+variables, then `read_seqcount_retry()` is called to confirm the two
+are consistent, and only then is `->d_compare()` called.  When
+standard filename comparison is used, `dentry_cmp()` is called
+instead.  Notably it does _not_ use `read_seqcount_retry()`, but
+instead has a large comment explaining why the consistency guarantee
+isn't necessary.  A subsequent `read_seqcount_retry()` will be
+sufficient to catch any problem that could occur at this point.
+
+With that little refresher on seqlocks out of the way we can look at
+the bigger picture of how RCU-walk uses seqlocks.
+
+### `mount_lock` and `nd->m_seq` ###
+
+We already met the `mount_lock` seqlock when REF-walk used it to
+ensure that crossing a mount point is performed safely.  RCU-walk uses
+it for that too, but for quite a bit more.
+
+Instead of taking a counted reference to each `vfsmount` as it
+descends the tree, RCU-walk samples the state of `mount_lock` at the
+start of the walk and stores this initial sequence number in the
+`struct nameidata` in the `m_seq` field.  This one lock and one
+sequence number are used to validate all accesses to all `vfsmounts`,
+and all mount point crossings.  As changes to the mount table are
+relatively rare, it is reasonable to fall back on REF-walk any time
+that any "mount" or "unmount" happens.
+
+`m_seq` is checked (using `read_seqretry()`) at the end of an RCU-walk
+sequence, whether switching to REF-walk for the rest of the path or
+when the end of the path is reached.  It is also checked when stepping
+down over a mount point (in `__follow_mount_rcu()`) or up (in
+`follow_dotdot_rcu()`).  If it is ever found to have changed, the
+whole RCU-walk sequence is aborted and the path is processed again by
+REF-walk.
+
+If RCU-walk finds that `mount_lock` hasn't changed then it can be sure
+that, had REF-walk taken counted references on each vfsmount, the
+results would have been the same.  This ensures the invariant holds,
+at least for vfsmount structures.
+
+### `dentry->d_seq` and `nd->seq`. ###
+
+In place of taking a count or lock on `d_reflock`, RCU-walk samples
+the per-dentry `d_seq` seqlock, and stores the sequence number in the
+`seq` field of the nameidata structure, so `nd->seq` should always be
+the current sequence number of `nd->dentry`.  This number needs to be
+revalidated after copying, and before using, the name, parent, or
+inode of the dentry.
+
+The handling of the name we have already looked at, and the parent is
+only accessed in `follow_dotdot_rcu()` which fairly trivially follows
+the required pattern, though it does so for three different cases.
+
+When not at a mount point, `d_parent` is followed and its `d_seq` is
+collected.  When we are at a mount point, we instead follow the
+`mnt->mnt_mountpoint` link to get a new dentry and collect its
+`d_seq`.  Then, after finally finding a `d_parent` to follow, we must
+check if we have landed on a mount point and, if so, must find that
+mount point and follow the `mnt->mnt_root` link.  This would imply a
+somewhat unusual, but certainly possible, circumstance where the
+starting point of the path lookup was in part of the filesystem that
+was mounted on, and so not visible from the root.
+
+The inode pointer, stored in `->d_inode`, is a little more
+interesting.  The inode will always need to be accessed at least
+twice, once to determine if it is NULL and once to verify access
+permissions.  Symlink handling requires a validated inode pointer too.
+Rather than revalidating on each access, a copy is made on the first
+access and it is stored in the `inode` field of `nameidata` from where
+it can be safely accessed without further validation.
+
+`lookup_fast()` is the only lookup routine that is used in RCU-mode,
+`lookup_slow()` being too slow and requiring locks.  It is in
+`lookup_fast()` that we find the important "hand over hand" tracking
+of the current dentry.
+
+The current `dentry` and current `seq` number are passed to
+`__d_lookup_rcu()` which, on success, returns a new `dentry` and a
+new `seq` number.  `lookup_fast()` then copies the inode pointer and
+revalidates the new `seq` number.  It then validates the old `dentry`
+with the old `seq` number one last time and only then continues.  This
+process of getting the `seq` number of the new dentry and then
+checking the `seq` number of the old exactly mirrors the process of
+getting a counted reference to the new dentry before dropping that for
+the old dentry which we saw in REF-walk.
+
+### No `inode->i_mutex` or even `rename_lock` ###
+
+A mutex is a fairly heavyweight lock that can only be taken when it is
+permissible to sleep.  As `rcu_read_lock()` forbids sleeping,
+`inode->i_mutex` plays no role in RCU-walk.  If some other thread does
+take `i_mutex` and modifies the directory in a way that RCU-walk needs
+to notice, the result will be either that RCU-walk fails to find the
+dentry that it is looking for, or it will find a dentry which
+`read_seqretry()` won't validate.  In either case it will drop down to
+REF-walk mode which can take whatever locks are needed.
+
+Though `rename_lock` could be used by RCU-walk as it doesn't require
+any sleeping, RCU-walk doesn't bother.  REF-walk uses `rename_lock` to
+protect against the possibility of hash chains in the dcache changing
+while they are being searched.  This can result in failing to find
+something that actually is there.  When RCU-walk fails to find
+something in the dentry cache, whether it is really there or not, it
+already drops down to REF-walk and tries again with appropriate
+locking.  This neatly handles all cases, so adding extra checks on
+rename_lock would bring no significant value.
+
+`unlazy walk()` and `complete_walk()`
+-------------------------------------
+
+That "dropping down to REF-walk" typically involves a call to
+`unlazy_walk()`, so named because "RCU-walk" is also sometimes
+referred to as "lazy walk".  `unlazy_walk()` is called when
+following the path down to the current vfsmount/dentry pair seems to
+have proceeded successfully, but the next step is problematic.  This
+can happen if the next name cannot be found in the dcache, if
+permission checking or name revalidation couldn't be achieved while
+the `rcu_read_lock()` is held (which forbids sleeping), if an
+automount point is found, or in a couple of cases involving symlinks.
+It is also called from `complete_walk()` when the lookup has reached
+the final component, or the very end of the path, depending on which
+particular flavor of lookup is used.
+
+Other reasons for dropping out of RCU-walk that do not trigger a call
+to `unlazy_walk()` are when some inconsistency is found that cannot be
+handled immediately, such as `mount_lock` or one of the `d_seq`
+seqlocks reporting a change.  In these cases the relevant function
+will return `-ECHILD` which will percolate up until it triggers a new
+attempt from the top using REF-walk.
+
+For those cases where `unlazy_walk()` is an option, it essentially
+takes a reference on each of the pointers that it holds (vfsmount,
+dentry, and possibly some symbolic links) and then verifies that the
+relevant seqlocks have not been changed.  If there have been changes,
+it, too, aborts with `-ECHILD`, otherwise the transition to REF-walk
+has been a success and the lookup process continues.
+
+Taking a reference on those pointers is not quite as simple as just
+incrementing a counter.  That works to take a second reference if you
+already have one (often indirectly through another object), but it
+isn't sufficient if you don't actually have a counted reference at
+all.  For `dentry->d_lockref`, it is safe to increment the reference
+counter to get a reference unless it has been explicitly marked as
+"dead" which involves setting the counter to `-128`.
+`lockref_get_not_dead()` achieves this.
+
+For `mnt->mnt_count` it is safe to take a reference as long as
+`mount_lock` is then used to validate the reference.  If that
+validation fails, it may *not* be safe to just drop that reference in
+the standard way of calling `mnt_put()` - an unmount may have
+progressed too far.  So the code in `legitimize_mnt()`, when it
+finds that the reference it got might not be safe, checks the
+`MNT_SYNC_UMOUNT` flag to determine if a simple `mnt_put()` is
+correct, or if it should just decrement the count and pretend none of
+this ever happened.
+
+Taking care in filesystems
+---------------------------
+
+RCU-walk depends almost entirely on cached information and often will
+not call into the filesystem at all.  However there are two places,
+besides the already-mentioned component-name comparison, where the
+file system might be included in RCU-walk, and it must know to be
+careful.
+
+If the filesystem has non-standard permission-checking requirements -
+such as a networked filesystem which may need to check with the server
+- the `i_op->permission` interface might be called during RCU-walk.
+In this case an extra "`MAY_NOT_BLOCK`" flag is passed so that it
+knows not to sleep, but to return `-ECHILD` if it cannot complete
+promptly.  `i_op->permission` is given the inode pointer, not the
+dentry, so it doesn't need to worry about further consistency checks.
+However if it accesses any other filesystem data structures, it must
+ensure they are safe to be accessed with only the `rcu_read_lock()`
+held.  This typically means they must be freed using `kfree_rcu()` or
+similar.
+
+[`READ_ONCE()`]: https://lwn.net/Articles/624126/
+
+If the filesystem may need to revalidate dcache entries, then
+`d_op->d_revalidate` may be called in RCU-walk too.  This interface
+*is* passed the dentry but does not have access to the `inode` or the
+`seq` number from the `nameidata`, so it needs to be extra careful
+when accessing fields in the dentry.  This "extra care" typically
+involves using `ACCESS_ONCE()` or the newer [`READ_ONCE()`] to access
+fields, and verifying the result is not NULL before using it.  This
+pattern can be see in `nfs_lookup_revalidate()`.
+
+A pair of patterns
+------------------
+
+In various places in the details of REF-walk and RCU-walk, and also in
+the big picture, there are a couple of related patterns that are worth
+being aware of.
+
+The first is "try quickly and check, if that fails try slowly".  We
+can see that in the high-level approach of first trying RCU-walk and
+then trying REF-walk, and in places where `unlazy_walk()` is used to
+switch to REF-walk for the rest of the path.  We also saw it earlier
+in `dget_parent()` when following a "`..`" link.  It tries a quick way
+to get a reference, then falls back to taking locks if needed.
+
+The second pattern is "try quickly and check, if that fails try
+again - repeatedly".  This is seen with the use of `rename_lock` and
+`mount_lock` in REF-walk.  RCU-walk doesn't make use of this pattern -
+if anything goes wrong it is much safer to just abort and try a more
+sedate approach.
+
+The emphasis here is "try quickly and check".  It should probably be
+"try quickly _and carefully,_ then check".  The fact that checking is
+needed is a reminder that the system is dynamic and only a limited
+number of things are safe at all.  The most likely cause of errors in
+this whole process is assuming something is safe when in reality it
+isn't.  Careful consideration of what exactly guarantees the safety of
+each access is sometimes necessary.
+
+A walk among the symlinks
+=========================
+
+There are several basic issues that we will examine to understand the
+handling of symbolic links:  the symlink stack, together with cache
+lifetimes, will help us understand the overall recursive handling of
+symlinks and lead to the special care needed for the final component.
+Then a consideration of access-time updates and summary of the various
+flags controlling lookup will finish the story.
+
+The symlink stack
+-----------------
+
+There are only two sorts of filesystem objects that can usefully
+appear in a path prior to the final component: directories and symlinks.
+Handling directories is quite straightforward: the new directory
+simply becomes the starting point at which to interpret the next
+component on the path.  Handling symbolic links requires a bit more
+work.
+
+Conceptually, symbolic links could be handled by editing the path.  If
+a component name refers to a symbolic link, then that component is
+replaced by the body of the link and, if that body starts with a '/',
+then all preceding parts of the path are discarded.  This is what the
+"`readlink -f`" command does, though it also edits out "`.`" and
+"`..`" components.
+
+Directly editing the path string is not really necessary when looking
+up a path, and discarding early components is pointless as they aren't
+looked at anyway.  Keeping track of all remaining components is
+important, but they can of course be kept separately; there is no need
+to concatenate them.  As one symlink may easily refer to another,
+which in turn can refer to a third, we may need to keep the remaining
+components of several paths, each to be processed when the preceding
+ones are completed.  These path remnants are kept on a stack of
+limited size.
+
+There are two reasons for placing limits on how many symlinks can
+occur in a single path lookup.  The most obvious is to avoid loops.
+If a symlink referred to itself either directly or through
+intermediaries, then following the symlink can never complete
+successfully - the error `ELOOP` must be returned.  Loops can be
+detected without imposing limits, but limits are the simplest solution
+and, given the second reason for restriction, quite sufficient.
+
+[outlined recently]: http://thread.gmane.org/gmane.linux.kernel/1934390/focus=1934550
+
+The second reason was [outlined recently] by Linus:
+
+>  Because it's a latency and DoS issue too. We need to react well to
+>  true loops, but also to "very deep" non-loops. It's not about memory
+>  use, it's about users triggering unreasonable CPU resources.
+
+Linux imposes a limit on the length of any pathname: `PATH_MAX`, which
+is 4096.  There are a number of reasons for this limit; not letting the
+kernel spend too much time on just one path is one of them.  With
+symbolic links you can effectively generate much longer paths so some
+sort of limit is needed for the same reason.  Linux imposes a limit of
+at most 40 symlinks in any one path lookup.  It previously imposed a
+further limit of eight on the maximum depth of recursion, but that was
+raised to 40 when a separate stack was implemented, so there is now
+just the one limit.
+
+The `nameidata` structure that we met in an earlier article contains a
+small stack that can be used to store the remaining part of up to two
+symlinks.  In many cases this will be sufficient.  If it isn't, a
+separate stack is allocated with room for 40 symlinks.  Pathname
+lookup will never exceed that stack as, once the 40th symlink is
+detected, an error is returned.
+
+It might seem that the name remnants are all that needs to be stored on
+this stack, but we need a bit more.  To see that, we need to move on to
+cache lifetimes.
+
+Storage and lifetime of cached symlinks
+---------------------------------------
+
+Like other filesystem resources, such as inodes and directory
+entries, symlinks are cached by Linux to avoid repeated costly access
+to external storage.  It is particularly important for RCU-walk to be
+able to find and temporarily hold onto these cached entries, so that
+it doesn't need to drop down into REF-walk.
+
+[object-oriented design pattern]: https://lwn.net/Articles/446317/
+
+While each filesystem is free to make its own choice, symlinks are
+typically stored in one of two places.  Short symlinks are often
+stored directly in the inode.  When a filesystem allocates a `struct
+inode` it typically allocates extra space to store private data (a
+common [object-oriented design pattern] in the kernel).  This will
+sometimes include space for a symlink.  The other common location is
+in the page cache, which normally stores the content of files.  The
+pathname in a symlink can be seen as the content of that symlink and
+can easily be stored in the page cache just like file content.
+
+When neither of these is suitable, the next most likely scenario is
+that the filesystem will allocate some temporary memory and copy or
+construct the symlink content into that memory whenever it is needed.
+
+When the symlink is stored in the inode, it has the same lifetime as
+the inode which, itself, is protected by RCU or by a counted reference
+on the dentry.  This means that the mechanisms that pathname lookup
+uses to access the dcache and icache (inode cache) safely are quite
+sufficient for accessing some cached symlinks safely.  In these cases,
+the `i_link` pointer in the inode is set to point to wherever the
+symlink is stored and it can be accessed directly whenever needed.
+
+When the symlink is stored in the page cache or elsewhere, the
+situation is not so straightforward.  A reference on a dentry or even
+on an inode does not imply any reference on cached pages of that
+inode, and even an `rcu_read_lock()` is not sufficient to ensure that
+a page will not disappear.  So for these symlinks the pathname lookup
+code needs to ask the filesystem to provide a stable reference and,
+significantly, needs to release that reference when it is finished
+with it.
+
+Taking a reference to a cache page is often possible even in RCU-walk
+mode.  It does require making changes to memory, which is best avoided,
+but that isn't necessarily a big cost and it is better than dropping
+out of RCU-walk mode completely.  Even filesystems that allocate
+space to copy the symlink into can use `GFP_ATOMIC` to often successfully
+allocate memory without the need to drop out of RCU-walk.  If a
+filesystem cannot successfully get a reference in RCU-walk mode, it
+must return `-ECHILD` and `unlazy_walk()` will be called to return to
+REF-walk mode in which the filesystem is allowed to sleep.
+
+The place for all this to happen is the `i_op->follow_link()` inode
+method.  In the present mainline code this is never actually called in
+RCU-walk mode as the rewrite is not quite complete.  It is likely that
+in a future release this method will be passed an `inode` pointer when
+called in RCU-walk mode so it both (1) knows to be careful, and (2) has the
+validated pointer.  Much like the `i_op->permission()` method we
+looked at previously, `->follow_link()` would need to be careful that
+all the data structures it references are safe to be accessed while
+holding no counted reference, only the RCU lock.  Though getting a
+reference with `->follow_link()` is not yet done in RCU-walk mode, the
+code is ready to release the reference when that does happen.
+
+This need to drop the reference to a symlink adds significant
+complexity.  It requires a reference to the inode so that the
+`i_op->put_link()` inode operation can be called.  In REF-walk, that
+reference is kept implicitly through a reference to the dentry, so
+keeping the `struct path` of the symlink is easiest.  For RCU-walk,
+the pointer to the inode is kept separately.  To allow switching from
+RCU-walk back to REF-walk in the middle of processing nested symlinks
+we also need the seq number for the dentry so we can confirm that
+switching back was safe.
+
+Finally, when providing a reference to a symlink, the filesystem also
+provides an opaque "cookie" that must be passed to `->put_link()` so that it
+knows what to free.  This might be the allocated memory area, or a
+pointer to the `struct page` in the page cache, or something else
+completely.  Only the filesystem knows what it is.
+
+In order for the reference to each symlink to be dropped when the walk completes,
+whether in RCU-walk or REF-walk, the symlink stack needs to contain,
+along with the path remnants:
+
+- the `struct path` to provide a reference to the inode in REF-walk
+- the `struct inode *` to provide a reference to the inode in RCU-walk
+- the `seq` to allow the path to be safely switched from RCU-walk to REF-walk
+- the `cookie` that tells `->put_path()` what to put.
+
+This means that each entry in the symlink stack needs to hold five
+pointers and an integer instead of just one pointer (the path
+remnant).  On a 64-bit system, this is about 40 bytes per entry;
+with 40 entries it adds up to 1600 bytes total, which is less than
+half a page.  So it might seem like a lot, but is by no means
+excessive.
+
+Note that, in a given stack frame, the path remnant (`name`) is not
+part of the symlink that the other fields refer to.  It is the remnant
+to be followed once that symlink has been fully parsed.
+
+Following the symlink
+---------------------
+
+The main loop in `link_path_walk()` iterates seamlessly over all
+components in the path and all of the non-final symlinks.  As symlinks
+are processed, the `name` pointer is adjusted to point to a new
+symlink, or is restored from the stack, so that much of the loop
+doesn't need to notice.  Getting this `name` variable on and off the
+stack is very straightforward; pushing and popping the references is
+a little more complex.
+
+When a symlink is found, `walk_component()` returns the value `1`
+(`0` is returned for any other sort of success, and a negative number
+is, as usual, an error indicator).  This causes `get_link()` to be
+called; it then gets the link from the filesystem.  Providing that
+operation is successful, the old path `name` is placed on the stack,
+and the new value is used as the `name` for a while.  When the end of
+the path is found (i.e. `*name` is `'\0'`) the old `name` is restored
+off the stack and path walking continues.
+
+Pushing and popping the reference pointers (inode, cookie, etc.) is more
+complex in part because of the desire to handle tail recursion.  When
+the last component of a symlink itself points to a symlink, we
+want to pop the symlink-just-completed off the stack before pushing
+the symlink-just-found to avoid leaving empty path remnants that would
+just get in the way.
+
+It is most convenient to push the new symlink references onto the
+stack in `walk_component()` immediately when the symlink is found;
+`walk_component()` is also the last piece of code that needs to look at the
+old symlink as it walks that last component.  So it is quite
+convenient for `walk_component()` to release the old symlink and pop
+the references just before pushing the reference information for the
+new symlink.  It is guided in this by two flags; `WALK_GET`, which
+gives it permission to follow a symlink if it finds one, and
+`WALK_PUT`, which tells it to release the current symlink after it has been
+followed.  `WALK_PUT` is tested first, leading to a call to
+`put_link()`.  `WALK_GET` is tested subsequently (by
+`should_follow_link()`) leading to a call to `pick_link()` which sets
+up the stack frame.
+
+### Symlinks with no final component ###
+
+A pair of special-case symlinks deserve a little further explanation.
+Both result in a new `struct path` (with mount and dentry) being set
+up in the `nameidata`, and result in `get_link()` returning `NULL`.
+
+The more obvious case is a symlink to "`/`".  All symlinks starting
+with "`/`" are detected in `get_link()` which resets the `nameidata`
+to point to the effective filesystem root.  If the symlink only
+contains "`/`" then there is nothing more to do, no components at all,
+so `NULL` is returned to indicate that the symlink can be released and
+the stack frame discarded.
+
+The other case involves things in `/proc` that look like symlinks but
+aren't really.
+
+>     $ ls -l /proc/self/fd/1
+>     lrwx------ 1 neilb neilb 64 Jun 13 10:19 /proc/self/fd/1 -> /dev/pts/4
+
+Every open file descriptor in any process is represented in `/proc` by
+something that looks like a symlink.  It is really a reference to the
+target file, not just the name of it.  When you `readlink` these
+objects you get a name that might refer to the same file - unless it
+has been unlinked or mounted over.  When `walk_component()` follows
+one of these, the `->follow_link()` method in "procfs" doesn't return
+a string name, but instead calls `nd_jump_link()` which updates the
+`nameidata` in place to point to that target.  `->follow_link()` then
+returns `NULL`.  Again there is no final component and `get_link()`
+reports this by leaving the `last_type` field of `nameidata` as
+`LAST_BIND`.
+
+Following the symlink in the final component
+--------------------------------------------
+
+All this leads to `link_path_walk()` walking down every component, and
+following all symbolic links it finds, until it reaches the final
+component.  This is just returned in the `last` field of `nameidata`.
+For some callers, this is all they need; they want to create that
+`last` name if it doesn't exist or give an error if it does.  Other
+callers will want to follow a symlink if one is found, and possibly
+apply special handling to the last component of that symlink, rather
+than just the last component of the original file name.  These callers
+potentially need to call `link_path_walk()` again and again on
+successive symlinks until one is found that doesn't point to another
+symlink.
+
+This case is handled by the relevant caller of `link_path_walk()`, such as
+`path_lookupat()` using a loop that calls `link_path_walk()`, and then
+handles the final component.  If the final component is a symlink
+that needs to be followed, then `trailing_symlink()` is called to set
+things up properly and the loop repeats, calling `link_path_walk()`
+again.  This could loop as many as 40 times if the last component of
+each symlink is another symlink.
+
+The various functions that examine the final component and possibly
+report that it is a symlink are `lookup_last()`, `mountpoint_last()`
+and `do_last()`, each of which use the same convention as
+`walk_component()` of returning `1` if a symlink was found that needs
+to be followed.
+
+Of these, `do_last()` is the most interesting as it is used for
+opening a file.  Part of `do_last()` runs with `i_mutex` held and this
+part is in a separate function: `lookup_open()`.
+
+Explaining `do_last()` completely is beyond the scope of this article,
+but a few highlights should help those interested in exploring the
+code.
+
+1. Rather than just finding the target file, `do_last()` needs to open
+ it.  If the file was found in the dcache, then `vfs_open()` is used for
+ this.  If not, then `lookup_open()` will either call `atomic_open()` (if
+ the filesystem provides it) to combine the final lookup with the open, or
+ will perform the separate `lookup_real()` and `vfs_create()` steps
+ directly.  In the later case the actual "open" of this newly found or
+ created file will be performed by `vfs_open()`, just as if the name
+ were found in the dcache.
+
+2. `vfs_open()` can fail with `-EOPENSTALE` if the cached information
+ wasn't quite current enough.  Rather than restarting the lookup from
+ the top with `LOOKUP_REVAL` set, `lookup_open()` is called instead,
+ giving the filesystem a chance to resolve small inconsistencies.
+ If that doesn't work, only then is the lookup restarted from the top.
+
+3. An open with O_CREAT **does** follow a symlink in the final component,
+     unlike other creation system calls (like `mkdir`).  So the sequence:
+
+     >     ln -s bar /tmp/foo
+     >     echo hello > /tmp/foo
+
+     will create a file called `/tmp/bar`.  This is not permitted if
+     `O_EXCL` is set but otherwise is handled for an O_CREAT open much
+     like for a non-creating open: `should_follow_link()` returns `1`, and
+     so does `do_last()` so that `trailing_symlink()` gets called and the
+     open process continues on the symlink that was found.
+
+Updating the access time
+------------------------
+
+We previously said of RCU-walk that it would "take no locks, increment
+no counts, leave no footprints."  We have since seen that some
+"footprints" can be needed when handling symlinks as a counted
+reference (or even a memory allocation) may be needed.  But these
+footprints are best kept to a minimum.
+
+One other place where walking down a symlink can involve leaving
+footprints in a way that doesn't affect directories is in updating access times.
+In Unix (and Linux) every filesystem object has a "last accessed
+time", or "`atime`".  Passing through a directory to access a file
+within is not considered to be an access for the purposes of
+`atime`; only listing the contents of a directory can update its `atime`.
+Symlinks are different it seems.  Both reading a symlink (with `readlink()`)
+and looking up a symlink on the way to some other destination can
+update the atime on that symlink.
+
+[clearest statement]: http://pubs.opengroup.org/onlinepubs/9699919799/basedefs/V1_chap04.html#tag_04_08
+
+It is not clear why this is the case; POSIX has little to say on the
+subject.  The [clearest statement] is that, if a particular implementation
+updates a timestamp in a place not specified by POSIX, this must be
+documented "except that any changes caused by pathname resolution need
+not be documented".  This seems to imply that POSIX doesn't really
+care about access-time updates during pathname lookup.
+
+[Linux 1.3.87]: https://git.kernel.org/cgit/linux/kernel/git/history/history.git/diff/fs/ext2/symlink.c?id=f806c6db77b8eaa6e00dcfb6b567706feae8dbb8
+
+An examination of history shows that prior to [Linux 1.3.87], the ext2
+filesystem, at least, didn't update atime when following a link.
+Unfortunately we have no record of why that behavior was changed.
+
+In any case, access time must now be updated and that operation can be
+quite complex.  Trying to stay in RCU-walk while doing it is best
+avoided.  Fortunately it is often permitted to skip the `atime`
+update.  Because `atime` updates cause performance problems in various
+areas, Linux supports the `relatime` mount option, which generally
+limits the updates of `atime` to once per day on files that aren't
+being changed (and symlinks never change once created).  Even without
+`relatime`, many filesystems record `atime` with a one-second
+granularity, so only one update per second is required.
+
+It is easy to test if an `atime` update is needed while in RCU-walk
+mode and, if it isn't, the update can be skipped and RCU-walk mode
+continues.  Only when an `atime` update is actually required does the
+path walk drop down to REF-walk.  All of this is handled in the
+`get_link()` function.
+
+A few flags
+-----------
+
+A suitable way to wrap up this tour of pathname walking is to list
+the various flags that can be stored in the `nameidata` to guide the
+lookup process.  Many of these are only meaningful on the final
+component, others reflect the current state of the pathname lookup.
+And then there is `LOOKUP_EMPTY`, which doesn't fit conceptually with
+the others.  If this is not set, an empty pathname causes an error
+very early on.  If it is set, empty pathnames are not considered to be
+an error.
+
+### Global state flags ###
+
+We have already met two global state flags: `LOOKUP_RCU` and
+`LOOKUP_REVAL`.  These select between one of three overall approaches
+to lookup: RCU-walk, REF-walk, and REF-walk with forced revalidation.
+
+`LOOKUP_PARENT` indicates that the final component hasn't been reached
+yet.  This is primarily used to tell the audit subsystem the full
+context of a particular access being audited.
+
+`LOOKUP_ROOT` indicates that the `root` field in the `nameidata` was
+provided by the caller, so it shouldn't be released when it is no
+longer needed.
+
+`LOOKUP_JUMPED` means that the current dentry was chosen not because
+it had the right name but for some other reason.  This happens when
+following "`..`", following a symlink to `/`, crossing a mount point
+or accessing a "`/proc/$PID/fd/$FD`" symlink.  In this case the
+filesystem has not been asked to revalidate the name (with
+`d_revalidate()`).  In such cases the inode may still need to be
+revalidated, so `d_op->d_weak_revalidate()` is called if
+`LOOKUP_JUMPED` is set when the look completes - which may be at the
+final component or, when creating, unlinking, or renaming, at the penultimate component.
+
+### Final-component flags ###
+
+Some of these flags are only set when the final component is being
+considered.  Others are only checked for when considering that final
+component.
+
+`LOOKUP_AUTOMOUNT` ensures that, if the final component is an automount
+point, then the mount is triggered.  Some operations would trigger it
+anyway, but operations like `stat()` deliberately don't.  `statfs()`
+needs to trigger the mount but otherwise behaves a lot like `stat()`, so
+it sets `LOOKUP_AUTOMOUNT`, as does "`quotactl()`" and the handling of
+"`mount --bind`".
+
+`LOOKUP_FOLLOW` has a similar function to `LOOKUP_AUTOMOUNT` but for
+symlinks.  Some system calls set or clear it implicitly, while
+others have API flags such as `AT_SYMLINK_FOLLOW` and
+`UMOUNT_NOFOLLOW` to control it.  Its effect is similar to
+`WALK_GET` that we already met, but it is used in a different way.
+
+`LOOKUP_DIRECTORY` insists that the final component is a directory.
+Various callers set this and it is also set when the final component
+is found to be followed by a slash.
+
+Finally `LOOKUP_OPEN`, `LOOKUP_CREATE`, `LOOKUP_EXCL`, and
+`LOOKUP_RENAME_TARGET` are not used directly by the VFS but are made
+available to the filesystem and particularly the `->d_revalidate()`
+method.  A filesystem can choose not to bother revalidating too hard
+if it knows that it will be asked to open or create the file soon.
+These flags were previously useful for `->lookup()` too but with the
+introduction of `->atomic_open()` they are less relevant there.
+
+End of the road
+---------------
+
+Despite its complexity, all this pathname lookup code appears to be
+in good shape - various parts are certainly easier to understand now
+than even a couple of releases ago.  But that doesn't mean it is
+"finished".   As already mentioned, RCU-walk currently only follows
+symlinks that are stored in the inode so, while it handles many ext4
+symlinks, it doesn't help with NFS, XFS, or Btrfs.  That support
+is not likely to be long delayed.

+FPGA Manager Core
+
+Alan Tull 2015
+
+Overview
+========
+
+The FPGA manager core exports a set of functions for programming an FPGA with
+an image.  The API is manufacturer agnostic.  All manufacturer specifics are
+hidden away in a low level driver which registers a set of ops with the core.
+The FPGA image data itself is very manufacturer specific, but for our purposes
+it's just binary data.  The FPGA manager core won't parse it.
+
+
+API Functions:
+==============
+
+To program the FPGA from a file or from a buffer:
+-------------------------------------------------
+
+	int fpga_mgr_buf_load(struct fpga_manager *mgr, u32 flags,
+		              const char *buf, size_t count);
+
+Load the FPGA from an image which exists as a buffer in memory.
+
+	int fpga_mgr_firmware_load(struct fpga_manager *mgr, u32 flags,
+		                   const char *image_name);
+
+Load the FPGA from an image which exists as a file.  The image file must be on
+the firmware search path (see the firmware class documentation).
+
+For both these functions, flags == 0 for normal full reconfiguration or
+FPGA_MGR_PARTIAL_RECONFIG for partial reconfiguration.  If successful, the FPGA
+ends up in operating mode.  Return 0 on success or a negative error code.
+
+
+To get/put a reference to a FPGA manager:
+-----------------------------------------
+
+	struct fpga_manager *of_fpga_mgr_get(struct device_node *node);
+
+	void fpga_mgr_put(struct fpga_manager *mgr);
+
+Given a DT node, get an exclusive reference to a FPGA manager or release
+the reference.
+
+
+To register or unregister the low level FPGA-specific driver:
+-------------------------------------------------------------
+
+	int fpga_mgr_register(struct device *dev, const char *name,
+		              const struct fpga_manager_ops *mops,
+		              void *priv);
+
+	void fpga_mgr_unregister(struct device *dev);
+
+Use of these two functions is described below in "How To Support a new FPGA
+device."
+

+
+/* Release the FPGA manager */
+fpga_mgr_put(mgr);
+
+
+How to support a new FPGA device
+================================
+To add another FPGA manager, write a driver that implements a set of ops.  The
+probe function calls fpga_mgr_register(), such as:
+
+static const struct fpga_manager_ops socfpga_fpga_ops = {
+       .write_init = socfpga_fpga_ops_configure_init,
+       .write = socfpga_fpga_ops_configure_write,
+       .write_complete = socfpga_fpga_ops_configure_complete,
+       .state = socfpga_fpga_ops_state,
+};
+
+static int socfpga_fpga_probe(struct platform_device *pdev)
+{
+	struct device *dev = &pdev->dev;
+	struct socfpga_fpga_priv *priv;
+	int ret;
+
+	priv = devm_kzalloc(dev, sizeof(*priv), GFP_KERNEL);
+	if (!priv)
+		return -ENOMEM;
+
+	/* ... do ioremaps, get interrupts, etc. and save
+	   them in priv... */
+
+	return fpga_mgr_register(dev, "Altera SOCFPGA FPGA Manager",
+				 &socfpga_fpga_ops, priv);
+}
+
+static int socfpga_fpga_remove(struct platform_device *pdev)
+{
+	fpga_mgr_unregister(&pdev->dev);
+
+	return 0;
+}
+
+
+The ops will implement whatever device specific register writes are needed to
+do the programming sequence for this particular FPGA.  These ops return 0 for
+success or negative error codes otherwise.
+
+The programming sequence is:
+ 1. .write_init
+ 2. .write (may be called once or multiple times)
+ 3. .write_complete
+
+The .write_init function will prepare the FPGA to receive the image data.
+
+The .write function writes a buffer to the FPGA. The buffer may be contain the
+whole FPGA image or may be a smaller chunk of an FPGA image.  In the latter
+case, this function is called multiple times for successive chunks.
+
+The .write_complete function is called after all the image has been written
+to put the FPGA into operating mode.
+
+The ops include a .state function which will read the hardware FPGA manager and
+return a code of type enum fpga_mgr_states.  It doesn't result in a change in
+hardware state.

+This driver implements support for the Maxim MAX31790 chip.
+
+The MAX31790 controls the speeds of up to six fans using six independent
+PWM outputs. The desired fan speeds (or PWM duty cycles) are written
+through the I2C interface. The outputs drive "4-wire" fans directly,
+or can be used to modulate the fan's power terminals using an external
+pass transistor.
+
+Tachometer inputs monitor fan tachometer logic outputs for precise (+/-1%)
+monitoring and control of fan RPM as well as detection of fan failure.
+Six pins are dedicated tachometer inputs. Any of the six PWM outputs can
+also be configured to serve as tachometer inputs.

+--------------------------------------------------------------------------------
+
+1. Introduction
+~~~~~~~~~~~~~~~
+  This module is intended to try to make the lives of input driver developers
+easier by allowing them to test various serio devices (mainly the various
+touchpads found on laptops) without having to have the physical device in front
+of them. userio accomplishes this by allowing any privileged userspace program
+to directly interact with the kernel's serio driver and control a virtual serio
+port from there.
+
+2. Usage overview
+~~~~~~~~~~~~~~~~~
+  In order to interact with the userio kernel module, one simply opens the
+/dev/userio character device in their applications. Commands are sent to the
+kernel module by writing to the device, and any data received from the serio
+driver is read as-is from the /dev/userio device. All of the structures and
+macros you need to interact with the device are defined in <linux/userio.h> and
+<linux/serio.h>.
+
+3. Command Structure
+~~~~~~~~~~~~~~~~~~~~
+  The struct used for sending commands to /dev/userio is as follows:
+
+	struct userio_cmd {
+		__u8 type;
+		__u8 data;
+	};
+
+  "type" describes the type of command that is being sent. This can be any one
+of the USERIO_CMD macros defined in <linux/userio.h>. "data" is the argument
+that goes along with the command. In the event that the command doesn't have an
+argument, this field can be left untouched and will be ignored by the kernel.
+Each command should be sent by writing the struct directly to the character
+device. In the event that the command you send is invalid, an error will be
+returned by the character device and a more descriptive error will be printed
+to the kernel log. Only one command can be sent at a time, any additional data
+written to the character device after the initial command will be ignored.
+  To close the virtual serio port, just close /dev/userio.
+
+4. Commands
+~~~~~~~~~~~
+
+4.1 USERIO_CMD_REGISTER
+~~~~~~~~~~~~~~~~~~~~~~~
+  Registers the port with the serio driver and begins transmitting data back and
+forth. Registration can only be performed once a port type is set with
+USERIO_CMD_SET_PORT_TYPE. Has no argument.
+
+4.2 USERIO_CMD_SET_PORT_TYPE
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Sets the type of port we're emulating, where "data" is the port type being
+set. Can be any of the macros from <linux/serio.h>. For example: SERIO_8042
+would set the port type to be a normal PS/2 port.
+
+4.3 USERIO_CMD_SEND_INTERRUPT
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+  Sends an interrupt through the virtual serio port to the serio driver, where
+"data" is the interrupt data being sent.
+
+5. Userspace tools
+~~~~~~~~~~~~~~~~~~
+  The userio userspace tools are able to record PS/2 devices using some of the
+debugging information from i8042, and play back the devices on /dev/userio. The
+latest version of these tools can be found at:

-  FIXME: Add details about the CAN FD controller configuration when available.
+  When configuring CAN FD capable CAN controllers an additional 'data' bitrate
+  has to be set. This bitrate for the data phase of the CAN FD frame has to be
+  at least the bitrate which was configured for the arbitration phase. This
+  second bitrate is specified analogue to the first bitrate but the bitrate
+  setting keywords for the 'data' bitrate start with 'd' e.g. dbitrate,
+  dsample-point, dsjw or dtq and similar settings. When a data bitrate is set
+  within the configuration process the controller option "fd on" can be
+  specified to enable the CAN FD mode in the CAN controller. This controller
+  option also switches the device MTU to 72 (CANFD_MTU).
+
+  The first CAN FD specification presented as whitepaper at the International
+  CAN Conference 2012 needed to be improved for data integrity reasons.
+  Therefore two CAN FD implementations have to be distinguished today:
+
+  - ISO compliant:     The ISO 11898-1:2015 CAN FD implementation (default)
+  - non-ISO compliant: The CAN FD implementation following the 2012 whitepaper
+
+  Finally there are three types of CAN FD controllers:
+
+  1. ISO compliant (fixed)
+  2. non-ISO compliant (fixed, like the M_CAN IP core v3.0.1 in m_can.c)
+  3. ISO/non-ISO CAN FD controllers (switchable, like the PEAK PCAN-USB FD)
+
+  The current ISO/non-ISO mode is announced by the CAN controller driver via
+  netlink and displayed by the 'ip' tool (controller option FD-NON-ISO).
+  The ISO/non-ISO-mode can be altered by setting 'fd-non-iso {on|off}' for
+  switchable CAN FD controllers only.

+################################################################################
+
+Using iproute2 for VRFs
+=======================
+VRF devices do *not* have to start with 'vrf-'. That is a convention used here
+for emphasis of the device type, similar to use of 'br' in bridge names.
+
+1. Create a VRF
+
+   To instantiate a VRF device and associate it with a table:
+       $ ip link add dev NAME type vrf table ID
+
+   Remember to add the ip rules as well:
+       $ ip ru add oif NAME table 10
+       $ ip ru add iif NAME table 10
+       $ ip -6 ru add oif NAME table 10
+       $ ip -6 ru add iif NAME table 10
+
+   Without the rules route lookups are not directed to the table.
+
+   For example:
+   $ ip link add dev vrf-blue type vrf table 10
+   $ ip ru add pref 200 oif vrf-blue table 10
+   $ ip ru add pref 200 iif vrf-blue table 10
+   $ ip -6 ru add pref 200 oif vrf-blue table 10
+   $ ip -6 ru add pref 200 iif vrf-blue table 10
+
+
+2. List VRFs
+
+   To list VRFs that have been created:
+       $ ip [-d] link show type vrf
+         NOTE: The -d option is needed to show the table id
+
+   For example:
+   $ ip -d link show type vrf
+   11: vrf-mgmt: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+       link/ether 72:b3:ba:91:e2:24 brd ff:ff:ff:ff:ff:ff promiscuity 0
+       vrf table 1 addrgenmode eui64
+   12: vrf-red: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+       link/ether b6:6f:6e:f6:da:73 brd ff:ff:ff:ff:ff:ff promiscuity 0
+       vrf table 10 addrgenmode eui64
+   13: vrf-blue: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+       link/ether 36:62:e8:7d:bb:8c brd ff:ff:ff:ff:ff:ff promiscuity 0
+       vrf table 66 addrgenmode eui64
+   14: vrf-green: <NOARP,MASTER,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
+       link/ether e6:28:b8:63:70:bb brd ff:ff:ff:ff:ff:ff promiscuity 0
+       vrf table 81 addrgenmode eui64
+
+
+   Or in brief output:
+
+   $ ip -br link show type vrf
+   vrf-mgmt         UP             72:b3:ba:91:e2:24 <NOARP,MASTER,UP,LOWER_UP>
+   vrf-red          UP             b6:6f:6e:f6:da:73 <NOARP,MASTER,UP,LOWER_UP>
+   vrf-blue         UP             36:62:e8:7d:bb:8c <NOARP,MASTER,UP,LOWER_UP>
+   vrf-green        UP             e6:28:b8:63:70:bb <NOARP,MASTER,UP,LOWER_UP>
+
+
+3. Assign a Network Interface to a VRF
+
+   Network interfaces are assigned to a VRF by enslaving the netdevice to a
+   VRF device:
+       $ ip link set dev NAME master VRF-NAME
+
+   On enslavement connected and local routes are automatically moved to the
+   table associated with the VRF device.
+
+   For example:
+   $ ip link set dev eth0 master vrf-mgmt
+
+
+4. Show Devices Assigned to a VRF
+
+   To show devices that have been assigned to a specific VRF add the master
+   option to the ip command:
+       $ ip link show master VRF-NAME
+
+   For example:
+   $ ip link show master vrf-red
+   3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP mode DEFAULT group default qlen 1000
+       link/ether 02:00:00:00:02:02 brd ff:ff:ff:ff:ff:ff
+   4: eth2: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP mode DEFAULT group default qlen 1000
+       link/ether 02:00:00:00:02:03 brd ff:ff:ff:ff:ff:ff
+   7: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop master vrf-red state DOWN mode DEFAULT group default qlen 1000

+5. Show Neighbor Entries for a VRF
+
+   To list neighbor entries associated with devices enslaved to a VRF device
+   add the master option to the ip command:
+       $ ip [-6] neigh show master VRF-NAME
+
+   For example:
+   $  ip neigh show master vrf-red
+   10.2.1.254 dev eth1 lladdr a6:d9:c7:4f:06:23 REACHABLE
+   10.2.2.254 dev eth2 lladdr 5e:54:01:6a:ee:80 REACHABLE
+
+    $ ip -6 neigh show master vrf-red
+    2002:1::64 dev eth1 lladdr a6:d9:c7:4f:06:23 REACHABLE
+
+
+6. Show Addresses for a VRF
+
+   To show addresses for interfaces associated with a VRF add the master
+   option to the ip command:
+       $ ip addr show master VRF-NAME
+
+   For example:
+   $ ip addr show master vrf-red
+   3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast master vrf-red state UP group default qlen 1000

+
+
+7. Show Routes for a VRF
+
+   To show routes for a VRF use the ip command to display the table associated
+   with the VRF device:
+       $ ip [-6] route show table ID
+
+   For example:
+   $ ip route show table vrf-red
+   prohibit default
+   broadcast 10.2.1.0 dev eth1  proto kernel  scope link  src 10.2.1.2
+   10.2.1.0/24 dev eth1  proto kernel  scope link  src 10.2.1.2
+   local 10.2.1.2 dev eth1  proto kernel  scope host  src 10.2.1.2
+   broadcast 10.2.1.255 dev eth1  proto kernel  scope link  src 10.2.1.2
+   broadcast 10.2.2.0 dev eth2  proto kernel  scope link  src 10.2.2.2
+   10.2.2.0/24 dev eth2  proto kernel  scope link  src 10.2.2.2
+   local 10.2.2.2 dev eth2  proto kernel  scope host  src 10.2.2.2
+   broadcast 10.2.2.255 dev eth2  proto kernel  scope link  src 10.2.2.2
+
+   $ ip -6 route show table vrf-red
+   local 2002:1:: dev lo  proto none  metric 0  pref medium
+   local 2002:1::2 dev lo  proto none  metric 0  pref medium
+   2002:1::/120 dev eth1  proto kernel  metric 256  pref medium
+   local 2002:2:: dev lo  proto none  metric 0  pref medium
+   local 2002:2::2 dev lo  proto none  metric 0  pref medium
+   2002:2::/120 dev eth2  proto kernel  metric 256  pref medium
+   local fe80:: dev lo  proto none  metric 0  pref medium
+   local fe80:: dev lo  proto none  metric 0  pref medium
+   local fe80::ff:fe00:202 dev lo  proto none  metric 0  pref medium
+   local fe80::ff:fe00:203 dev lo  proto none  metric 0  pref medium
+   fe80::/64 dev eth1  proto kernel  metric 256  pref medium
+   fe80::/64 dev eth2  proto kernel  metric 256  pref medium
+   ff00::/8 dev vrf-red  metric 256  pref medium
+   ff00::/8 dev eth1  metric 256  pref medium
+   ff00::/8 dev eth2  metric 256  pref medium
+
+
+8. Route Lookup for a VRF
+
+   A test route lookup can be done for a VRF by adding the oif option to ip:
+       $ ip [-6] route get oif VRF-NAME ADDRESS
+
+   For example:
+   $ ip route get 10.2.1.40 oif vrf-red
+   10.2.1.40 dev eth1  table vrf-red  src 10.2.1.2
+       cache
+
+   $ ip -6 route get 2002:1::32 oif vrf-red
+   2002:1::32 from :: dev eth1  table vrf-red  proto kernel  src 2002:1::2  metric 256  pref medium
+
+
+9. Removing Network Interface from a VRF
+
+   Network interfaces are removed from a VRF by breaking the enslavement to
+   the VRF device:
+       $ ip link set dev NAME nomaster
+
+   Connected routes are moved back to the default table and local entries are
+   moved to the local table.
+
+   For example:
+   $ ip link set dev eth0 nomaster
+

+The runtime PM of PCI devices is enabled by default by the PCI core.  PCI
+device drivers do not need to enable it and should not attempt to do so.
+However, it is blocked by pci_pm_init() that runs the pm_runtime_forbid()
+helper function.  In addition to that, the runtime PM usage counter of
+each PCI device is incremented by local_pci_probe() before executing the
+probe callback provided by the device's driver.
+
+If a PCI driver implements the runtime PM callbacks and intends to use the
+runtime PM framework provided by the PM core and the PCI subsystem, it needs
+to decrement the device's runtime PM usage counter in its probe callback
+function.  If it doesn't do that, the counter will always be different from
+zero for the device and it will never be runtime-suspended.  The simplest
+way to do that is by calling pm_runtime_put_noidle(), but if the driver
+wants to schedule an autosuspend right away, for example, it may call
+pm_runtime_put_autosuspend() instead for this purpose.  Generally, it
+just needs to call a function that decrements the devices usage counter
+from its probe routine to make runtime PM work for the device.
+
+It is important to remember that the driver's runtime_suspend() callback
+may be executed right after the usage counter has been decremented, because
+user space may already have cuased the pm_runtime_allow() helper function
+unblocking the runtime PM of the device to run via sysfs, so the driver must
+be prepared to cope with that.
+
+The driver itself should not call pm_runtime_allow(), though.  Instead, it
+should let user space or some platform-specific code do that (user space can
+do it via sysfs as stated above), but it must be prepared to handle the
 runtime PM of the device correctly as soon as pm_runtime_allow() is called
-(which may happen at any time).  [It also is possible that user space causes
-pm_runtime_allow() to be called via sysfs before the driver is loaded, so in
-fact the driver has to be prepared to handle the runtime PM of the device as
-soon as it calls pm_runtime_enable().]
+(which may happen at any time, even before the driver is loaded).
+
+When the driver's remove callback runs, it has to balance the decrementation
+of the device's runtime PM usage counter at the probe time.  For this reason,
+if it has decremented the counter in its probe callback, it must run
+pm_runtime_get_noresume() in its remove callback.  [Since the core carries
+out a runtime resume of the device and bumps up the device's usage counter
+before running the driver's remove callback, the runtime PM of the device
+is effectively disabled for the duration of the remove execution and all
+runtime PM helper functions incrementing the device's usage counter are
+then effectively equivalent to pm_runtime_get_noresume().]
 
 The runtime PM framework works by processing requests to suspend or resume
 devices, or to check if they are idle (in which cases it is reasonable to

-Notes on Universal Interface for Intel High Definition Audio Codec
-------------------------------------------------------------------
-
-Takashi Iwai <tiwai@suse.de>
-
-
-[Still a draft version]
-
-
-General
-=======
-
-The snd-hda-codec module supports the generic access function for the
-High Definition (HD) audio codecs.  It's designed to be independent
-from the controller code like ac97 codec module.  The real accessors
-from/to the controller must be implemented in the lowlevel driver.
-
-The structure of this module is similar with ac97_codec module.
-Each codec chip belongs to a bus class which communicates with the
-controller.
-
-
-Initialization of Bus Instance
-==============================
-
-The card driver has to create struct hda_bus at first.  The template
-struct should be filled and passed to the constructor:
-
-struct hda_bus_template {
-	void *private_data;
-	struct pci_dev *pci;
-	const char *modelname;
-	struct hda_bus_ops ops;
-};
-
-The card driver can set and use the private_data field to retrieve its
-own data in callback functions.  The pci field is used when the patch
-needs to check the PCI subsystem IDs, so on.  For non-PCI system, it
-doesn't have to be set, of course.
-The modelname field specifies the board's specific configuration.  The
-string is passed to the codec parser, and it depends on the parser how
-the string is used.
-These fields, private_data, pci and modelname are all optional.
-
-The ops field contains the callback functions as the following:
-
-struct hda_bus_ops {
-	int (*command)(struct hda_codec *codec, hda_nid_t nid, int direct,
-		       unsigned int verb, unsigned int parm);
-	unsigned int (*get_response)(struct hda_codec *codec);
-	void (*private_free)(struct hda_bus *);
-#ifdef CONFIG_SND_HDA_POWER_SAVE
-	void (*pm_notify)(struct hda_codec *codec);
-#endif
-};
-
-The command callback is called when the codec module needs to send a
-VERB to the controller.  It's always a single command.
-The get_response callback is called when the codec requires the answer
-for the last command.  These two callbacks are mandatory and have to
-be given.
-The third, private_free callback, is optional.  It's called in the
-destructor to release any necessary data in the lowlevel driver.
-
-The pm_notify callback is available only with
-CONFIG_SND_HDA_POWER_SAVE kconfig.  It's called when the codec needs
-to power up or may power down.  The controller should check the all
-belonging codecs on the bus whether they are actually powered off
-(check codec->power_on), and optionally the driver may power down the
-controller side, too.
-
-The bus instance is created via snd_hda_bus_new().  You need to pass
-the card instance, the template, and the pointer to store the
-resultant bus instance.
-
-int snd_hda_bus_new(struct snd_card *card, const struct hda_bus_template *temp,
-		    struct hda_bus **busp);
-
-It returns zero if successful.  A negative return value means any
-error during creation.
-
-
-Creation of Codec Instance
-==========================
-
-Each codec chip on the board is then created on the BUS instance.
-To create a codec instance, call snd_hda_codec_new().
-
-int snd_hda_codec_new(struct hda_bus *bus, unsigned int codec_addr,
-		      struct hda_codec **codecp);
-
-The first argument is the BUS instance, the second argument is the
-address of the codec, and the last one is the pointer to store the
-resultant codec instance (can be NULL if not needed).
-
-The codec is stored in a linked list of bus instance.  You can follow
-the codec list like:
-
-	struct hda_codec *codec;
-	list_for_each_entry(codec, &bus->codec_list, list) {
-		...
-	}
-
-The codec isn't initialized at this stage properly.  The
-initialization sequence is called when the controls are built later.
-
-
-Codec Access
-============
-
-To access codec, use snd_hda_codec_read() and snd_hda_codec_write().
-snd_hda_param_read() is for reading parameters.
-For writing a sequence of verbs, use snd_hda_sequence_write().
-
-There are variants of cached read/write, snd_hda_codec_write_cache(),
-snd_hda_sequence_write_cache().  These are used for recording the
-register states for the power-management resume.  When no PM is needed,
-these are equivalent with non-cached version.
-
-To retrieve the number of sub nodes connected to the given node, use
-snd_hda_get_sub_nodes().  The connection list can be obtained via
-snd_hda_get_connections() call.
-
-When an unsolicited event happens, pass the event via
-snd_hda_queue_unsol_event() so that the codec routines will process it
-later.
-
-
-(Mixer) Controls
-================
-
-To create mixer controls of all codecs, call
-snd_hda_build_controls().  It then builds the mixers and does
-initialization stuff on each codec.
-
-
-PCM Stuff
-=========
-
-snd_hda_build_pcms() gives the necessary information to create PCM
-streams.  When it's called, each codec belonging to the bus stores 
-codec->num_pcms and codec->pcm_info fields.  The num_pcms indicates
-the number of elements in pcm_info array.  The card driver is supposed
-to traverse the codec linked list, read the pcm information in
-pcm_info array, and build pcm instances according to them. 
-
-The pcm_info array contains the following record:
-
-/* PCM information for each substream */
-struct hda_pcm_stream {
-	unsigned int substreams;	/* number of substreams, 0 = not exist */
-	unsigned int channels_min;	/* min. number of channels */
-	unsigned int channels_max;	/* max. number of channels */
-	hda_nid_t nid;	/* default NID to query rates/formats/bps, or set up */
-	u32 rates;	/* supported rates */
-	u64 formats;	/* supported formats (SNDRV_PCM_FMTBIT_) */
-	unsigned int maxbps;	/* supported max. bit per sample */
-	struct hda_pcm_ops ops;
-};
-
-/* for PCM creation */
-struct hda_pcm {
-	char *name;
-	struct hda_pcm_stream stream[2];
-};
-
-The name can be passed to snd_pcm_new().  The stream field contains
-the information  for playback (SNDRV_PCM_STREAM_PLAYBACK = 0) and
-capture (SNDRV_PCM_STREAM_CAPTURE = 1) directions.  The card driver
-should pass substreams to snd_pcm_new() for the number of substreams
-to create.
-
-The channels_min, channels_max, rates and formats should be copied to
-runtime->hw record.  They and maxbps fields are used also to compute
-the format value for the HDA codec and controller.  Call
-snd_hda_calc_stream_format() to get the format value.
-
-The ops field contains the following callback functions:
-
-struct hda_pcm_ops {
-	int (*open)(struct hda_pcm_stream *info, struct hda_codec *codec,
-		    struct snd_pcm_substream *substream);
-	int (*close)(struct hda_pcm_stream *info, struct hda_codec *codec,
-		     struct snd_pcm_substream *substream);
-	int (*prepare)(struct hda_pcm_stream *info, struct hda_codec *codec,
-		       unsigned int stream_tag, unsigned int format,
-		       struct snd_pcm_substream *substream);
-	int (*cleanup)(struct hda_pcm_stream *info, struct hda_codec *codec,
-		       struct snd_pcm_substream *substream);
-};
-
-All are non-NULL, so you can call them safely without NULL check.
-
-The open callback should be called in PCM open after runtime->hw is
-set up.  It may override some setting and constraints additionally.
-Similarly, the close callback should be called in the PCM close.
-
-The prepare callback should be called in PCM prepare.  This will set
-up the codec chip properly for the operation.  The cleanup should be
-called in hw_free to clean up the configuration.
-
-The caller should check the return value, at least for open and
-prepare callbacks.  When a negative value is returned, some error
-occurred.
-
-
-Proc Files
-==========
-
-Each codec dumps the widget node information in
-/proc/asound/card*/codec#* file.  This information would be really
-helpful for debugging.  Please provide its contents together with the
-bug report.
-
-
-Power Management
-================
-
-It's simple:
-Call snd_hda_suspend() in the PM suspend callback.
-Call snd_hda_resume() in the PM resume callback.
-
-
-Codec Preset (Patch)
-====================
-
-To set up and handle the codec functionality fully, each codec may
-have a codec preset (patch).  It's defined in struct hda_codec_preset:
-
-	struct hda_codec_preset {
-		unsigned int id;
-		unsigned int mask;
-		unsigned int subs;
-		unsigned int subs_mask;
-		unsigned int rev;
-		const char *name;
-		int (*patch)(struct hda_codec *codec);
-	};
-
-When the codec id and codec subsystem id match with the given id and
-subs fields bitwise (with bitmask mask and subs_mask), the callback
-patch is called.  The patch callback should initialize the codec and
-set the codec->patch_ops field.  This is defined as below:
-
-	struct hda_codec_ops {
-		int (*build_controls)(struct hda_codec *codec);
-		int (*build_pcms)(struct hda_codec *codec);
-		int (*init)(struct hda_codec *codec);
-		void (*free)(struct hda_codec *codec);
-		void (*unsol_event)(struct hda_codec *codec, unsigned int res);
-	#ifdef CONFIG_PM
-		int (*suspend)(struct hda_codec *codec, pm_message_t state);
-		int (*resume)(struct hda_codec *codec);
-	#endif
-	#ifdef CONFIG_SND_HDA_POWER_SAVE
-		int (*check_power_status)(struct hda_codec *codec,
-					  hda_nid_t nid);
-	#endif
-	};
-
-The build_controls callback is called from snd_hda_build_controls().
-Similarly, the build_pcms callback is called from
-snd_hda_build_pcms().  The init callback is called after
-build_controls to initialize the hardware.
-The free callback is called as a destructor.
-
-The unsol_event callback is called when an unsolicited event is
-received.
-
-The suspend and resume callbacks are for power management.
-They can be NULL if no special sequence is required.  When the resume
-callback is NULL, the driver calls the init callback and resumes the
-registers from the cache.  If other handling is needed, you'd need to
-write your own resume callback.  There, the amp values can be resumed
-via
-	void snd_hda_codec_resume_amp(struct hda_codec *codec);
-and the other codec registers via
-	void snd_hda_codec_resume_cache(struct hda_codec *codec);
-
-The check_power_status callback is called when the amp value of the
-given widget NID is changed.  The codec code can turn on/off the power
-appropriately from this information.
-
-Each entry can be NULL if not necessary to be called.
-
-
-Generic Parser
-==============
-
-When the device doesn't match with any given presets, the widgets are
-parsed via th generic parser (hda_generic.c).  Its support is
-limited: no multi-channel support, for example.
-
-
-Digital I/O
-===========
-
-Call snd_hda_create_spdif_out_ctls() from the patch to create controls
-related with SPDIF out.
-
-
-Helper Functions
-================
-
-snd_hda_get_codec_name() stores the codec name on the given string.
-
-snd_hda_check_board_config() can be used to obtain the configuration
-information matching with the device.  Define the model string table
-and the table with struct snd_pci_quirk entries (zero-terminated),
-and pass it to the function.  The function checks the modelname given
-as a module parameter, and PCI subsystem IDs.  If the matching entry
-is found, it returns the config field value.
-
-snd_hda_add_new_ctls() can be used to create and add control entries.
-Pass the zero-terminated array of struct snd_kcontrol_new
-
-Macros HDA_CODEC_VOLUME(), HDA_CODEC_MUTE() and their variables can be
-used for the entry of struct snd_kcontrol_new.
-
-The input MUX helper callbacks for such a control are provided, too:
-snd_hda_input_mux_info() and snd_hda_input_mux_put().  See
-patch_realtek.c for example.

+Intel(R) Trace Hub (TH)
+=======================
+
+Overview
+--------
+
+Intel(R) Trace Hub (TH) is a set of hardware blocks that produce,
+switch and output trace data from multiple hardware and software
+sources over several types of trace output ports encoded in System
+Trace Protocol (MIPI STPv2) and is intended to perform full system
+debugging. For more information on the hardware, see Intel(R) Trace
+Hub developer's manual [1].
+
+It consists of trace sources, trace destinations (outputs) and a
+switch (Global Trace Hub, GTH). These devices are placed on a bus of
+their own ("intel_th"), where they can be discovered and configured
+via sysfs attributes.
+
+Currently, the following Intel TH subdevices (blocks) are supported:
+  - Software Trace Hub (STH), trace source, which is a System Trace
+  Module (STM) device,
+  - Memory Storage Unit (MSU), trace output, which allows storing
+  trace hub output in system memory,
+  - Parallel Trace Interface output (PTI), trace output to an external
+  debug host via a PTI port,
+  - Global Trace Hub (GTH), which is a switch and a central component
+  of Intel(R) Trace Hub architecture.
+
+Common attributes for output devices are described in
+Documentation/ABI/testing/sysfs-bus-intel_th-output-devices, the most
+notable of them is "active", which enables or disables trace output
+into that particular output device.
+
+GTH allows directing different STP masters into different output ports
+via its "masters" attribute group. More detailed GTH interface
+description is at Documentation/ABI/testing/sysfs-bus-intel_th-devices-gth.
+
+STH registers an stm class device, through which it provides interface
+to userspace and kernelspace software trace sources. See
+Documentation/tracing/stm.txt for more information on that.
+
+MSU can be configured to collect trace data into a system memory
+buffer, which can later on be read from its device nodes via read() or
+mmap() interface.
+
+On the whole, Intel(R) Trace Hub does not require any special
+userspace software to function; everything can be configured, started
+and collected via sysfs attributes, and device nodes.
+
+[1] https://software.intel.com/sites/default/files/managed/d3/3c/intel-th-developer-manual.pdf
+
+Bus and Subdevices
+------------------
+
+For each Intel TH device in the system a bus of its own is
+created and assigned an id number that reflects the order in which TH
+devices were emumerated. All TH subdevices (devices on intel_th bus)
+begin with this id: 0-gth, 0-msc0, 0-msc1, 0-pti, 0-sth, which is
+followed by device's name and an optional index.
+
+Output devices also get a device node in /dev/intel_thN, where N is
+the Intel TH device id. For example, MSU's memory buffers, when
+allocated, are accessible via /dev/intel_th0/msc{0,1}.
+
+Quick example
+-------------
+
+# figure out which GTH port is the first memory controller:
+
+$ cat /sys/bus/intel_th/devices/0-msc0/port
+0
+
+# looks like it's port 0, configure master 33 to send data to port 0:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-gth/masters/33
+
+# allocate a 2-windowed multiblock buffer on the first memory
+# controller, each with 64 pages:
+
+$ echo multi > /sys/bus/intel_th/devices/0-msc0/mode
+$ echo 64,64 > /sys/bus/intel_th/devices/0-msc0/nr_pages
+
+# enable wrapping for this controller, too:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/wrap
+
+# and enable tracing into this port:
+
+$ echo 1 > /sys/bus/intel_th/devices/0-msc0/active
+
+# .. send data to master 33, see stm.txt for more details ..
+# .. wait for traces to pile up ..
+# .. and stop the trace:
+
+$ echo 0 > /sys/bus/intel_th/devices/0-msc0/active
+
+# and now you can collect the trace from the device node:
+
+$ cat /dev/intel_th0/msc0 > my_stp_trace

+System Trace Module
+===================
+
+System Trace Module (STM) is a device described in MIPI STP specs as
+STP trace stream generator. STP (System Trace Protocol) is a trace
+protocol multiplexing data from multiple trace sources, each one of
+which is assigned a unique pair of master and channel. While some of
+these masters and channels are statically allocated to certain
+hardware trace sources, others are available to software. Software
+trace sources are usually free to pick for themselves any
+master/channel combination from this pool.
+
+On the receiving end of this STP stream (the decoder side), trace
+sources can only be identified by master/channel combination, so in
+order for the decoder to be able to make sense of the trace that
+involves multiple trace sources, it needs to be able to map those
+master/channel pairs to the trace sources that it understands.
+
+For instance, it is helpful to know that syslog messages come on
+master 7 channel 15, while arbitrary user applications can use masters
+48 to 63 and channels 0 to 127.
+
+To solve this mapping problem, stm class provides a policy management
+mechanism via configfs, that allows defining rules that map string
+identifiers to ranges of masters and channels. If these rules (policy)
+are consistent with what decoder expects, it will be able to properly
+process the trace data.
+
+This policy is a tree structure containing rules (policy_node) that
+have a name (string identifier) and a range of masters and channels
+associated with it, located in "stp-policy" subsystem directory in
+configfs. The topmost directory's name (the policy) is formatted as
+the STM device name to which this policy applies and and arbitrary
+string identifier separated by a stop. From the examle above, a rule
+may look like this:
+
+$ ls /config/stp-policy/dummy_stm.my-policy/user
+channels masters
+$ cat /config/stp-policy/dummy_stm.my-policy/user/masters
+48 63
+$ cat /config/stp-policy/dummy_stm.my-policy/user/channels
+0 127
+
+which means that the master allocation pool for this rule consists of
+masters 48 through 63 and channel allocation pool has channels 0
+through 127 in it. Now, any producer (trace source) identifying itself
+with "user" identification string will be allocated a master and
+channel from within these ranges.
+
+These rules can be nested, for example, one can define a rule "dummy"
+under "user" directory from the example above and this new rule will
+be used for trace sources with the id string of "user/dummy".
+
+Trace sources have to open the stm class device's node and write their
+trace data into its file descriptor. In order to identify themselves
+to the policy, they need to do a STP_POLICY_ID_SET ioctl on this file
+descriptor providing their id string. Otherwise, they will be
+automatically allocated a master/channel pair upon first write to this
+file descriptor according to the "default" rule of the policy, if such
+exists.
+
+Some STM devices may allow direct mapping of the channel mmio regions
+to userspace for zero-copy writing. One mappable page (in terms of
+mmu) will usually contain multiple channels' mmios, so the user will
+need to allocate that many channels to themselves (via the
+aforementioned ioctl() call) to be able to do this. That is, if your
+stm device's channel mmio region is 64 bytes and hardware page size is
+4096 bytes, after a successful STP_POLICY_ID_SET ioctl() call with
+width==64, you should be able to mmap() one page on this file
+descriptor and obtain direct access to an mmio region for 64 channels.
+
+For kernel-based trace sources, there is "stm_source" device
+class. Devices of this class can be connected and disconnected to/from
+stm devices at runtime via a sysfs attribute.
+
+Examples of STM devices are Intel(R) Trace Hub [1] and Coresight STM
+[2].

+Interface authorization
+-----------------------
+There is a similar approach to allow or deny specific USB interfaces.
+That allows to block only a subset of an USB device.
+
+Authorize an interface:
+$ echo 1 > /sys/bus/usb/devices/INTERFACE/authorized

+KVM/ARM VGIC Forwarded Physical Interrupts
+==========================================
+
+The KVM/ARM code implements software support for the ARM Generic
+Interrupt Controller's (GIC's) hardware support for virtualization by
+allowing software to inject virtual interrupts to a VM, which the guest
+OS sees as regular interrupts.  The code is famously known as the VGIC.
+
+Some of these virtual interrupts, however, correspond to physical
+interrupts from real physical devices.  One example could be the
+architected timer, which itself supports virtualization, and therefore
+lets a guest OS program the hardware device directly to raise an
+interrupt at some point in time.  When such an interrupt is raised, the
+host OS initially handles the interrupt and must somehow signal this
+event as a virtual interrupt to the guest.  Another example could be a
+passthrough device, where the physical interrupts are initially handled
+by the host, but the device driver for the device lives in the guest OS
+and KVM must therefore somehow inject a virtual interrupt on behalf of
+the physical one to the guest OS.
+
+These virtual interrupts corresponding to a physical interrupt on the
+host are called forwarded physical interrupts, but are also sometimes
+referred to as 'virtualized physical interrupts' and 'mapped interrupts'.
+
+Forwarded physical interrupts are handled slightly differently compared
+to virtual interrupts generated purely by a software emulated device.
+
+
+The HW bit
+----------
+Virtual interrupts are signalled to the guest by programming the List
+Registers (LRs) on the GIC before running a VCPU.  The LR is programmed
+with the virtual IRQ number and the state of the interrupt (Pending,
+Active, or Pending+Active).  When the guest ACKs and EOIs a virtual
+interrupt, the LR state moves from Pending to Active, and finally to
+inactive.
+
+The LRs include an extra bit, called the HW bit.  When this bit is set,
+KVM must also program an additional field in the LR, the physical IRQ
+number, to link the virtual with the physical IRQ.
+
+When the HW bit is set, KVM must EITHER set the Pending OR the Active
+bit, never both at the same time.
+
+Setting the HW bit causes the hardware to deactivate the physical
+interrupt on the physical distributor when the guest deactivates the
+corresponding virtual interrupt.
+
+
+Forwarded Physical Interrupts Life Cycle
+----------------------------------------
+
+The state of forwarded physical interrupts is managed in the following way:
+
+  - The physical interrupt is acked by the host, and becomes active on
+    the physical distributor (*).
+  - KVM sets the LR.Pending bit, because this is the only way the GICV
+    interface is going to present it to the guest.
+  - LR.Pending will stay set as long as the guest has not acked the interrupt.
+  - LR.Pending transitions to LR.Active on the guest read of the IAR, as
+    expected.
+  - On guest EOI, the *physical distributor* active bit gets cleared,
+    but the LR.Active is left untouched (set).
+  - KVM clears the LR on VM exits when the physical distributor
+    active state has been cleared.
+
+(*): The host handling is slightly more complicated.  For some forwarded
+interrupts (shared), KVM directly sets the active state on the physical
+distributor before entering the guest, because the interrupt is never actually
+handled on the host (see details on the timer as an example below).  For other
+forwarded interrupts (non-shared) the host does not deactivate the interrupt
+when the host ISR completes, but leaves the interrupt active until the guest
+deactivates it.  Leaving the interrupt active is allowed, because Linux
+configures the physical GIC with EOIMode=1, which causes EOI operations to
+perform a priority drop allowing the GIC to receive other interrupts of the
+default priority.
+
+
+Forwarded Edge and Level Triggered PPIs and SPIs
+------------------------------------------------
+Forwarded physical interrupts injected should always be active on the
+physical distributor when injected to a guest.
+
+Level-triggered interrupts will keep the interrupt line to the GIC
+asserted, typically until the guest programs the device to deassert the
+line.  This means that the interrupt will remain pending on the physical
+distributor until the guest has reprogrammed the device.  Since we
+always run the VM with interrupts enabled on the CPU, a pending
+interrupt will exit the guest as soon as we switch into the guest,
+preventing the guest from ever making progress as the process repeats
+over and over.  Therefore, the active state on the physical distributor
+must be set when entering the guest, preventing the GIC from forwarding
+the pending interrupt to the CPU.  As soon as the guest deactivates the
+interrupt, the physical line is sampled by the hardware again and the host
+takes a new interrupt if and only if the physical line is still asserted.
+
+Edge-triggered interrupts do not exhibit the same problem with
+preventing guest execution that level-triggered interrupts do.  One
+option is to not use HW bit at all, and inject edge-triggered interrupts
+from a physical device as pure virtual interrupts.  But that would
+potentially slow down handling of the interrupt in the guest, because a
+physical interrupt occurring in the middle of the guest ISR would
+preempt the guest for the host to handle the interrupt.  Additionally,
+if you configure the system to handle interrupts on a separate physical
+core from that running your VCPU, you still have to interrupt the VCPU
+to queue the pending state onto the LR, even though the guest won't use
+this information until the guest ISR completes.  Therefore, the HW
+bit should always be set for forwarded edge-triggered interrupts.  With
+the HW bit set, the virtual interrupt is injected and additional
+physical interrupts occurring before the guest deactivates the interrupt
+simply mark the state on the physical distributor as Pending+Active.  As
+soon as the guest deactivates the interrupt, the host takes another
+interrupt if and only if there was a physical interrupt between injecting
+the forwarded interrupt to the guest and the guest deactivating the
+interrupt.
+
+Consequently, whenever we schedule a VCPU with one or more LRs with the
+HW bit set, the interrupt must also be active on the physical
+distributor.
+
+
+Forwarded LPIs
+--------------
+LPIs, introduced in GICv3, are always edge-triggered and do not have an
+active state.  They become pending when a device signal them, and as
+soon as they are acked by the CPU, they are inactive again.
+
+It therefore doesn't make sense, and is not supported, to set the HW bit
+for physical LPIs that are forwarded to a VM as virtual interrupts,
+typically virtual SPIs.
+
+For LPIs, there is no other choice than to preempt the VCPU thread if
+necessary, and queue the pending state onto the LR.
+
+
+Putting It Together: The Architected Timer
+------------------------------------------
+The architected timer is a device that signals interrupts with level
+triggered semantics.  The timer hardware is directly accessed by VCPUs
+which program the timer to fire at some point in time.  Each VCPU on a
+system programs the timer to fire at different times, and therefore the
+hardware is multiplexed between multiple VCPUs.  This is implemented by
+context-switching the timer state along with each VCPU thread.
+
+However, this means that a scenario like the following is entirely
+possible, and in fact, typical:
+
+1.  KVM runs the VCPU
+2.  The guest programs the time to fire in T+100
+3.  The guest is idle and calls WFI (wait-for-interrupts)
+4.  The hardware traps to the host
+5.  KVM stores the timer state to memory and disables the hardware timer
+6.  KVM schedules a soft timer to fire in T+(100 - time since step 2)
+7.  KVM puts the VCPU thread to sleep (on a waitqueue)
+8.  The soft timer fires, waking up the VCPU thread
+9.  KVM reprograms the timer hardware with the VCPU's values
+10. KVM marks the timer interrupt as active on the physical distributor
+11. KVM injects a forwarded physical interrupt to the guest
+12. KVM runs the VCPU
+
+Notice that KVM injects a forwarded physical interrupt in step 11 without
+the corresponding interrupt having actually fired on the host.  That is
+exactly why we mark the timer interrupt as active in step 10, because
+the active state on the physical distributor is part of the state
+belonging to the timer hardware, which is context-switched along with
+the VCPU thread.
+
+If the guest does not idle because it is busy, the flow looks like this
+instead:
+
+1.  KVM runs the VCPU
+2.  The guest programs the time to fire in T+100
+4.  At T+100 the timer fires and a physical IRQ causes the VM to exit
+    (note that this initially only traps to EL2 and does not run the host ISR
+    until KVM has returned to the host).
+5.  With interrupts still disabled on the CPU coming back from the guest, KVM
+    stores the virtual timer state to memory and disables the virtual hw timer.
+6.  KVM looks at the timer state (in memory) and injects a forwarded physical
+    interrupt because it concludes the timer has expired.
+7.  KVM marks the timer interrupt as active on the physical distributor
+7.  KVM enables the timer, enables interrupts, and runs the VCPU
+
+Notice that again the forwarded physical interrupt is injected to the
+guest without having actually been handled on the host.  In this case it
+is because the physical interrupt is never actually seen by the host because the
+timer is disabled upon guest return, and the virtual forwarded interrupt is
+injected on the KVM guest entry path.

+Extended slabinfo mode and plotting
+-----------------------------------
+
+The slabinfo tool has a special 'extended' ('-X') mode that includes:
+ - Slabcache Totals
+ - Slabs sorted by size (up to -N <num> slabs, default 1)
+ - Slabs sorted by loss (up to -N <num> slabs, default 1)
+
+Additionally, in this mode slabinfo does not dynamically scale sizes (G/M/K)
+and reports everything in bytes (this functionality is also available to
+other slabinfo modes via '-B' option) which makes reporting more precise and
+accurate. Moreover, in some sense the `-X' mode also simplifies the analysis
+of slabs' behaviour, because its output can be plotted using the
+slabinfo-gnuplot.sh script. So it pushes the analysis from looking through
+the numbers (tons of numbers) to something easier -- visual analysis.
+
+To generate plots:
+a) collect slabinfo extended records, for example:
+
+  while [ 1 ]; do slabinfo -X >> FOO_STATS; sleep 1; done
+
+b) pass stats file(-s) to slabinfo-gnuplot.sh script:
+  slabinfo-gnuplot.sh FOO_STATS [FOO_STATS2 .. FOO_STATSN]
+
+The slabinfo-gnuplot.sh script will pre-processes the collected records
+and generates 3 png files (and 3 pre-processing cache files) per STATS
+file:
+ - Slabcache Totals: FOO_STATS-totals.png
+ - Slabs sorted by size: FOO_STATS-slabs-by-size.png
+ - Slabs sorted by loss: FOO_STATS-slabs-by-loss.png
+
+Another use case, when slabinfo-gnuplot can be useful, is when you need
+to compare slabs' behaviour "prior to" and "after" some code modification.
+To help you out there, slabinfo-gnuplot.sh script can 'merge' the
+`Slabcache Totals` sections from different measurements. To visually
+compare N plots:
+
+a) Collect as many STATS1, STATS2, .. STATSN files as you need
+  while [ 1 ]; do slabinfo -X >> STATS<X>; sleep 1; done
+
+b) Pre-process those STATS files
+  slabinfo-gnuplot.sh STATS1 STATS2 .. STATSN
+
+c) Execute slabinfo-gnuplot.sh in '-t' mode, passing all of the
+generated pre-processed *-totals
+  slabinfo-gnuplot.sh -t STATS1-totals STATS2-totals .. STATSN-totals
+
+This will produce a single plot (png file).
+
+Plots, expectedly, can be large so some fluctuations or small spikes
+can go unnoticed. To deal with that, `slabinfo-gnuplot.sh' has two
+options to 'zoom-in'/'zoom-out':
+ a) -s %d,%d  overwrites the default image width and heigh
+ b) -r %d,%d  specifies a range of samples to use (for example,
+              in `slabinfo -X >> FOO_STATS; sleep 1;' case, using
+              a "-r 40,60" range will plot only samples collected
+              between 40th and 60th seconds).

 try_to_unmap() is always called, by either vmscan for reclaim or for page

-
- (*) try_to_unmap_anon()
-
-     To unmap anonymous pages, each VMA in the list anchored in the anon_vma
-     must be visited - at least until a VM_LOCKED VMA is encountered.  If the
-     page is being unmapped for migration, VM_LOCKED VMAs do not stop the
-     process because mlocked pages are migratable.  However, for reclaim, if
-     the page is mapped into a VM_LOCKED VMA, the scan stops.
-
-     try_to_unmap_anon() attempts to acquire in read mode the mmap semaphore of
-     the mm_struct to which the VMA belongs.  If this is successful, it will
-     mlock the page via mlock_vma_page() - we wouldn't have gotten to
-     try_to_unmap_anon() if the page were already mlocked - and will return
-     SWAP_MLOCK, indicating that the page is unevictable.
-
-     If the mmap semaphore cannot be acquired, we are not sure whether the page
-     is really unevictable or not.  In this case, try_to_unmap_anon() will
-     return SWAP_AGAIN.
-
- (*) try_to_unmap_file() - linear mappings
-
-     Unmapping of a mapped file page works the same as for anonymous mappings,
-     except that the scan visits all VMAs that map the page's index/page offset
-     in the page's mapping's reverse map priority search tree.  It also visits
-     each VMA in the page's mapping's non-linear list, if the list is
-     non-empty.
-
-     As for anonymous pages, on encountering a VM_LOCKED VMA for a mapped file
-     page, try_to_unmap_file() will attempt to acquire the associated
-     mm_struct's mmap semaphore to mlock the page, returning SWAP_MLOCK if this
-     is successful, and SWAP_AGAIN, if not.
-
- (*) try_to_unmap_file() - non-linear mappings
-
-     If a page's mapping contains a non-empty non-linear mapping VMA list, then
-     try_to_un{map|lock}() must also visit each VMA in that list to determine
-     whether the page is mapped in a VM_LOCKED VMA.  Again, the scan must visit
-     all VMAs in the non-linear list to ensure that the pages is not/should not
-     be mlocked.
-
-     If a VM_LOCKED VMA is found in the list, the scan could terminate.
-     However, there is no easy way to determine whether the page is actually
-     mapped in a given VMA - either for unmapping or testing whether the
-     VM_LOCKED VMA actually pins the page.
-
-     try_to_unmap_file() handles non-linear mappings by scanning a certain
-     number of pages - a "cluster" - in each non-linear VMA associated with the
-     page's mapping, for each file mapped page that vmscan tries to unmap.  If
-     this happens to unmap the page we're trying to unmap, try_to_unmap() will
-     notice this on return (page_mapcount(page) will be 0) and return
-     SWAP_SUCCESS.  Otherwise, it will return SWAP_AGAIN, causing vmscan to
-     recirculate this page.  We take advantage of the cluster scan in
-     try_to_unmap_cluster() as follows:
-
-	For each non-linear VMA, try_to_unmap_cluster() attempts to acquire the
-	mmap semaphore of the associated mm_struct for read without blocking.
-
-	If this attempt is successful and the VMA is VM_LOCKED,
-	try_to_unmap_cluster() will retain the mmap semaphore for the scan;
-	otherwise it drops it here.
-
-	Then, for each page in the cluster, if we're holding the mmap semaphore
-	for a locked VMA, try_to_unmap_cluster() calls mlock_vma_page() to
-	mlock the page.  This call is a no-op if the page is already locked,
-	but will mlock any pages in the non-linear mapping that happen to be
-	unlocked.
-
-	If one of the pages so mlocked is the page passed in to try_to_unmap(),
-	try_to_unmap_cluster() will return SWAP_MLOCK, rather than the default
-	SWAP_AGAIN.  This will allow vmscan to cull the page, rather than
-	recirculating it on the inactive list.
-
-	Again, if try_to_unmap_cluster() cannot acquire the VMA's mmap sem, it
-	returns SWAP_AGAIN, indicating that the page is mapped by a VM_LOCKED
-	VMA, but couldn't be mlocked.
+functions handle anonymous and mapped file and KSM pages, as these types of
+pages have different reverse map lookup mechanisms, with different locking.
+In each case, whether rmap_walk_anon() or rmap_walk_file() or rmap_walk_ksm(),
+it will call try_to_unmap_one() for every VMA which might contain the page.
+
+When trying to reclaim, if try_to_unmap_one() finds the page in a VM_LOCKED
+VMA, it will then mlock the page via mlock_vma_page() instead of unmapping it,
+and return SWAP_MLOCK to indicate that the page is unevictable: and the scan
+stops there.
+
+mlock_vma_page() is called while holding the page table's lock (in addition
+to the page lock, and the rmap lock): to serialize against concurrent mlock or
+munlock or munmap system calls, mm teardown (munlock_vma_pages_all), reclaim,
+holepunching, and truncation of file pages and their anonymous COWed pages.

+ * kmap() API provides sleep semantics hence refered to as "permanent maps"
+ * It allows mapping LAST_PKMAP pages, using @last_pkmap_nr as the cursor
+ * for book-keeping
+ *
+ * kmap_atomic() can't sleep (calls pagefault_disable()), thus it provides
+ * shortlived ala "temporary mappings" which historically were implemented as
+ * fixmaps (compile time addr etc). Their book-keeping is done per cpu.
+ *
+ *	Both these facts combined (preemption disabled and per-cpu allocation)
+ *	means the total number of concurrent fixmaps will be limited to max
+ *	such allocations in a single control path. Thus KM_TYPE_NR (another
+ *	historic relic) is a small'ish number which caps max percpu fixmaps

+ * ARC HIGHMEM Details
+ *
+ * - the kernel vaddr space from 0x7z to 0x8z (currently used by vmalloc/module)
+ *   is now shared between vmalloc and kmap (non overlapping though)
+ *
+ * - Both fixmap/pkmap use a dedicated page table each, hooked up to swapper PGD
+ *   This means each only has 1 PGDIR_SIZE worth of kvaddr mappings, which means
+ *   2M of kvaddr space for typical config (8K page and 11:8:13 traversal split)
+ *
+ * - fixmap anyhow needs a limited number of mappings. So 2M kvaddr == 256 PTE
+ *   slots across NR_CPUS would be more than sufficient (generic code defines
+ *   KM_TYPE_NR as 20).
+ *
+ * - pkmap being preemptible, in theory could do with more than 256 concurrent
+ *   mappings. However, generic pkmap code: map_new_virtual(), doesn't traverse
+ *   the PGD and only works with a single page table @pkmap_page_table, hence

-*!
-*! FILE NAME  : i2c.c
-*!
-*! DESCRIPTION: implements an interface for IIC/I2C, both directly from other
-*!              kernel modules (i2c_writereg/readreg) and from userspace using
-*!              ioctl()'s
-*!
-*! Nov 30 1998  Torbjorn Eliasson  Initial version.
-*!              Bjorn Wesen        Elinux kernel version.
-*! Jan 14 2000  Johan Adolfsson    Fixed PB shadow register stuff -
-*!                                 don't use PB_I2C if DS1302 uses same bits,
-*!                                 use PB.
-*| June 23 2003 Pieter Grimmerink  Added 'i2c_sendnack'. i2c_readreg now
-*|                                 generates nack on last received byte,
-*|                                 instead of ack.
-*|                                 i2c_getack changed data level while clock
-*|                                 was high, causing DS75 to see  a stop condition

+ * This file export cstate related free running (read-only) counters
+ * for perf. These counters may be use simultaneously by other tools,
+ * such as turbostat. However, it still make sense to implement them
+ * in perf. Because we can conveniently collect them together with
+ * other events, and allow to use them from tools without special MSR
+ * access code.
+ *
+ * The events only support system-wide mode counting. There is no
+ * sampling support because it is not supported by the hardware.
+ *
+ * According to counters' scope and category, two PMUs are registered
+ * with the perf_event core subsystem.
+ *  - 'cstate_core': The counter is available for each physical core.
+ *    The counters include CORE_C*_RESIDENCY.
+ *  - 'cstate_pkg': The counter is available for each physical package.
+ *    The counters include PKG_C*_RESIDENCY.
+ *
+ * All of these counters are specified in the Intel® 64 and IA-32
+ * Architectures Software Developer.s Manual Vol3b.
+ *

+ * include some static integer values.
+ *
+ * CPU performance is on an abstract continuous scale as against a discretized
+ * P-state scale which is tied to CPU frequency only. In brief, the basic
+ * operation involves:
+ *
+ * - OS makes a CPU performance request. (Can provide min and max bounds)
+ *
+ * - Platform (such as BMC) is free to optimize request within requested bounds
+ *   depending on power/thermal budgets etc.
+ *
+ * - Platform conveys its decision back to OS
+ *
+ * The communication between OS and platform occurs through another medium
+ * called (PCC) Platform Communication Channel. This is a generic mailbox like
+ * mechanism which includes doorbell semantics to indicate register updates.
+ * See drivers/mailbox/pcc.c for details on PCC.
+ *
+ * Finer details about the PCC and CPPC spec are available in the ACPI v5.1 and

+/**
+ * DOC: BCM2835 CPRMAN (clock manager for the "audio" domain)
+ *
+ * The clock tree on the 2835 has several levels.  There's a root
+ * oscillator running at 19.2Mhz.  After the oscillator there are 5
+ * PLLs, roughly divided as "camera", "ARM", "core", "DSI displays",
+ * and "HDMI displays".  Those 5 PLLs each can divide their output to
+ * produce up to 4 channels.  Finally, there is the level of clocks to
+ * be consumed by other hardware components (like "H264" or "HDMI
+ * state machine"), which divide off of some subset of the PLL
+ * channels.
+ *
+ * All of the clocks in the tree are exposed in the DT, because the DT
+ * may want to make assignments of the final layer of clocks to the
+ * PLL channels, and some components of the hardware will actually
+ * skip layers of the tree (for example, the pixel clock comes
+ * directly from the PLLH PIX channel without using a CM_*CTL clock
+ * generator).

+ * @buffer2_length:	Length of the TS data in buffer2.
+ * @source:		Indicates which TS feed is the source of the callback.
+ *
+ * This function callback prototype, provided by the client of the demux API,
+ * is called from the demux code. The function is only called when filtering
+ * on ae TS feed has been enabled using the start_filtering() function at
+ * the &dmx_demux.
+ * Any TS packets that match the filter settings are copied to a circular
+ * buffer. The filtered TS packets are delivered to the client using this
+ * callback function. The size of the circular buffer is controlled by the
+ * circular_buffer_size parameter of the &dmx_ts_feed.@set function.
+ * It is expected that the @buffer1 and @buffer2 callback parameters point to
+ * addresses within the circular buffer, but other implementations are also
+ * possible. Note that the called party should not try to free the memory
+ * the @buffer1 and @buffer2 parameters point to.
+ *
+ * When this function is called, the @buffer1 parameter typically points to
+ * the start of the first undelivered TS packet within a circular buffer.
+ * The @buffer2 buffer parameter is normally NULL, except when the received
+ * TS packets have crossed the last address of the circular buffer and
+ * �wrapped� to the beginning of the buffer. In the latter case the @buffer1
+ * parameter would contain an address within the circular buffer, while the
+ * @buffer2 parameter would contain the first address of the circular buffer.
+ * The number of bytes delivered with this function (i.e. @buffer1_length +
+ * @buffer2_length) is usually equal to the value of callback_length parameter
+ * given in the set() function, with one exception: if a timeout occurs before
+ * receiving callback_length bytes of TS data, any undelivered packets are
+ * immediately delivered to the client by calling this function. The timeout
+ * duration is controlled by the set() function in the TS Feed API.
+ *
+ * If a TS packet is received with errors that could not be fixed by the
+ * TS-level forward error correction (FEC), the Transport_error_indicator
+ * flag of the TS packet header should be set. The TS packet should not be
+ * discarded, as the error can possibly be corrected by a higher layer
+ * protocol. If the called party is slow in processing the callback, it
+ * is possible that the circular buffer eventually fills up. If this happens,
+ * the demux driver should discard any TS packets received while the buffer
+ * is full and return -EOVERFLOW.
+ *
+ * The type of data returned to the callback can be selected by the
+ * &dmx_ts_feed.@set function. The type parameter decides if the raw
+ * TS packet (TS_PACKET) or just the payload (TS_PACKET|TS_PAYLOAD_ONLY)
+ * should be returned. If additionally the TS_DECODER bit is set the stream
+ * will also be sent to the hardware MPEG decoder.
+ *
+ * Return:
+ * 	0, on success;
+ * 	-EOVERFLOW, on buffer overflow.

+ * implementation should maintain a circular buffer for received sections.

+ *
+ * @allocate_ts_feed: Allocates a new TS feed, which is used to filter the TS

+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	The @callback function parameter contains a pointer to the callback
+ *	function for passing received TS packet.
+ *	It returns

+ *		-ERESTARTSYS, if mutex lock was interrupted;
+ *		-EBUSY, if no more TS feeds is available;

+ *
+ * @release_ts_feed: Releases the resources allocated with @allocate_ts_feed.
+ *	Any filtering in progress on the TS feed should be stopped before

+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	It returns
+ *		0 on success;
+ *		-EINVAL on bad parameter.
+ *
+ * @allocate_section_feed: Allocates a new section feed, i.e. a demux resource
+ *	for filtering and receiving sections. On platforms with hardware
+ *	support for section filtering, a section feed is directly mapped to
+ *	the demux HW. On other platforms, TS packets are first PID filtered in
+ *	hardware and a hardware section filter then emulated in software. The
+ *	caller obtains an API pointer of type dmx_section_feed_t as an out
+ *	parameter. Using this API the caller can set filtering parameters and
+ *	start receiving sections.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	The @callback function parameter contains a pointer to the callback
+ *	function for passing received TS packet.
+ *	It returns
+ *		0 on success;
+ *		-EBUSY, if no more TS feeds is available;
+ *		-EINVAL, on bad parameter.
+ *
+ * @release_section_feed: Releases the resources allocated with
+ *	@allocate_section_feed, including allocated filters. Any filtering in
+ *	progress on the section feed should be stopped before calling this
+ *	function.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @feed function parameter contains a pointer to the TS feed API and
+ *	instance data.
+ *	It returns
+ *		0 on success;
+ *		-EINVAL, on bad parameter.
+ *
+ * @add_frontend: Registers a connectivity between a demux and a front-end,
+ *	i.e., indicates that the demux can be connected via a call to
+ *	@connect_frontend to use the given front-end as a TS source. The
+ *	client of this function has to allocate dynamic or static memory for
+ *	the frontend structure and initialize its fields before calling this
+ *	function. This function is normally called during the driver
+ *	initialization. The caller must not free the memory of the frontend
+ *	struct before successfully calling @remove_frontend.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @frontend function parameter contains a pointer to the front-end
+ *	instance data.
+ *	It returns
+ *		0 on success;
+ *		-EINVAL, on bad parameter.
+ *
+ * @remove_frontend: Indicates that the given front-end, registered by a call
+ *	to @add_frontend, can no longer be connected as a TS source by this
+ *	demux. The function should be called when a front-end driver or a demux
+ *	driver is removed from the system. If the front-end is in use, the
+ *	function fails with the return value of -EBUSY. After successfully
+ *	calling this function, the caller can free the memory of the frontend
+ *	struct if it was dynamically allocated before the @add_frontend
+ *	operation.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @frontend function parameter contains a pointer to the front-end
+ *	instance data.
+ *	It returns
+ *		0 on success;
+ *		-ENODEV, if the front-end was not found,
+ *		-EINVAL, on bad parameter.
+ *
+ * @get_frontends: Provides the APIs of the front-ends that have been
+ *	registered for this demux. Any of the front-ends obtained with this
+ *	call can be used as a parameter for @connect_frontend. The include
+ *	file demux.h contains the macro DMX_FE_ENTRY() for converting an
+ *	element of the generic type struct &list_head * to the type
+ *	struct &dmx_frontend *. The caller must not free the memory of any of
+ *	the elements obtained via this function call.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	It returns a struct list_head pointer to the list of front-end
+ *	interfaces, or NULL in the case of an empty list.
+ *
+ * @connect_frontend: Connects the TS output of the front-end to the input of
+ *	the demux. A demux can only be connected to a front-end registered to
+ *	the demux with the function @add_frontend. It may or may not be
+ *	possible to connect multiple demuxes to the same front-end, depending
+ *	on the capabilities of the HW platform. When not used, the front-end
+ *	should be released by calling @disconnect_frontend.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	The @frontend function parameter contains a pointer to the front-end
+ *	instance data.
+ *	It returns
+ *		0 on success;
+ *		-EINVAL, on bad parameter.
+ *
+ * @disconnect_frontend: Disconnects the demux and a front-end previously
+ *	connected by a @connect_frontend call.
+ *	The @demux function parameter contains a pointer to the demux API and
+ *	instance data.
+ *	It returns
+ *		0 on success;
+ *		-EINVAL on bad parameter.
+ *
+ * @get_pes_pids: Get the PIDs for DMX_PES_AUDIO0, DMX_PES_VIDEO0,
+ *	DMX_PES_TELETEXT0, DMX_PES_SUBTITLE0 and DMX_PES_PCR0.
+ *	The @demux function parameter contains a pointer to the demux API and

+
+/*
+ * The COSM driver uses SCIF to communicate between the management node and the
+ * MIC cards. SCIF is used to (a) Send a shutdown command to the card (b)
+ * receive a shutdown status back from the card upon completion of shutdown and
+ * (c) receive periodic heartbeat messages from the card used to deduce if the
+ * card has crashed.
+ *
+ * A COSM server consisting of a SCIF listening endpoint waits for incoming
+ * connections from the card. Upon acceptance of the connection, a separate
+ * work-item is scheduled to handle SCIF message processing for that card. The
+ * life-time of this work-item is therefore the time from which the connection
+ * from a card is accepted to the time at which the connection is closed. A new
+ * work-item starts each time the card boots and is alive till the card (a)
+ * shuts down (b) is reset (c) crashes (d) cosm_client driver on the card is
+ * unloaded.
+ *
+ * From the point of view of COSM interactions with SCIF during card
+ * shutdown, reset and crash are as follows:
+ *
+ * Card shutdown
+ * -------------
+ * 1. COSM client on the card invokes orderly_poweroff() in response to SHUTDOWN
+ *    message from the host.
+ * 2. Card driver shutdown callback invokes scif_unregister_device(..) resulting
+ *    in scif_remove(..) getting called on the card
+ * 3. scif_remove -> scif_stop -> scif_handle_remove_node ->
+ *    scif_peer_unregister_device -> device_unregister for the host peer device
+ * 4. During device_unregister remove(..) method of cosm_client is invoked which
+ *    closes the COSM SCIF endpoint on the card. This results in a SCIF_DISCNCT
+ *    message being sent to host SCIF. SCIF_DISCNCT message processing on the
+ *    host SCIF sets the host COSM SCIF endpoint state to DISCONNECTED and wakes
+ *    up the host COSM thread blocked in scif_poll(..) resulting in
+ *    scif_poll(..)  returning POLLHUP.
+ * 5. On the card, scif_peer_release_dev is next called which results in an
+ *    SCIF_EXIT message being sent to the host and after receiving the
+ *    SCIF_EXIT_ACK from the host the peer device teardown on the card is
+ *    complete.
+ * 6. As part of the SCIF_EXIT message processing on the host, host sends a
+ *    SCIF_REMOVE_NODE to itself corresponding to the card being removed. This
+ *    starts a similar SCIF peer device teardown sequence on the host
+ *    corresponding to the card being shut down.
+ *
+ * Card reset
+ * ----------
+ * The case of interest here is when the card has not been previously shut down
+ * since most of the steps below are skipped in that case:
+
+ * 1. cosm_stop(..) invokes hw_ops->stop(..) method of the base PCIe driver
+ *    which unregisters the SCIF HW device resulting in scif_remove(..) being
+ *    called on the host.
+ * 2. scif_remove(..) calls scif_disconnect_node(..) which results in a
+ *    SCIF_EXIT message being sent to the card.
+ * 3. The card executes scif_stop() as part of SCIF_EXIT message
+ *    processing. This results in the COSM endpoint on the card being closed and
+ *    the SCIF host peer device on the card getting unregistered similar to
+ *    steps 3, 4 and 5 for the card shutdown case above. scif_poll(..) on the
+ *    host returns POLLHUP as a result.
+ * 4. On the host, card peer device unregister and SCIF HW remove(..) also
+ *    subsequently complete.
+ *
+ * Card crash
+ * ----------
+ * If a reset is issued after the card has crashed, there is no SCIF_DISCNT
+ * message from the card which would result in scif_poll(..) returning
+ * POLLHUP. In this case when the host SCIF driver sends a SCIF_REMOVE_NODE
+ * message to itself resulting in the card SCIF peer device being unregistered,
+ * this results in a scif_peer_release_dev -> scif_cleanup_scifdev->
+ * scif_invalidate_ep call sequence which sets the endpoint state to
+ * DISCONNECTED and results in scif_poll(..) returning POLLHUP.

+ * Note:
+ * 1/ ECC algorithms are working on pre-defined block sizes which are usually
+ *    different from the NAND page size. When fixing bitflips, ECC engines will
+ *    report the number of errors per chunk, and the NAND core infrastructure
+ *    expect you to return the maximum number of bitflips for the whole page.
+ *    This is why you should always use this function on a single chunk and
+ *    not on the whole page. After checking each chunk you should update your
+ *    max_bitflips value accordingly.
+ * 2/ When checking for bitflips in erased pages you should not only check
+ *    the payload data but also their associated ECC data, because a user might
+ *    have programmed almost all bits to 1 but a few. In this case, we
+ *    shouldn't consider the chunk as erased, and checking ECC bytes prevent
+ *    this case.
+ * 3/ The extraoob argument is optional, and should be used if some of your OOB
+ *    data are protected by the ECC engine.
+ *    It could also be used if you support subpages and want to attach some
+ *    extra OOB data to an ECC chunk.
+ *

+	---help---
+	  This is an alternative driver for various Realtek RTL8XXX
+	  parts written to utilize the Linux mac80211 stack.
+	  The driver is known to work with a number of RTL8723AU,
+	  RL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU devices
+
+	  This driver is under development and has a limited feature
+	  set. In particular it does not yet support 40MHz channels
+	  and power management. However it should have a smaller
+	  memory footprint than the vendor drivers and benetifs
+	  from the in kernel mac80211 stack.
+
+	  It can coexist with drivers from drivers/staging/rtl8723au,
+	  drivers/staging/rtl8192u, and drivers/net/wireless/rtlwifi,
+	  but you will need to control which module you wish to load.
+
+	  To compile this driver as a module, choose M here: the module will
+	  be called r8xxxu.  If unsure, say N.
+
+config RTL8XXXU_UNTESTED
+	bool "Include support for untested Realtek 8xxx USB devices (EXPERIMENTAL)"

+	  This option enables detection of Realtek 8723/8188/8191/8192 WiFi

+ * @HCI_CLEAR_ALL_PIPES: Allow to execute a HCI clear all pipes command.
+ *	It does not consider any NFC_ATTR_VENDOR_DATA.
+ * @HCI_DM_PUT_DATA: Allow to configure specific CLF registry as for example
+ *	RF trimmings or low level drivers configurations (I2C, SPI, SWP).
+ * @HCI_DM_UPDATE_AID: Allow to configure an AID routing into the CLF routing
+ *	table following RF technology, CLF mode or protocol.
+ * @HCI_DM_GET_INFO: Allow to retrieve CLF information.
+ * @HCI_DM_GET_DATA: Allow to retrieve CLF configurable data such as low
+ *	level drivers configurations or RF trimmings.
+ * @HCI_DM_DIRECT_LOAD: Allow to load a firmware into the CLF. A complete
+ *	packet can be more than 8KB.
+ * @HCI_DM_RESET: Allow to run a CLF reset in order to "commit" CLF
+ *	configuration changes without CLF power off.
+ * @HCI_GET_PARAM: Allow to retrieve an HCI CLF parameter (for example the
+ *	white list).
+ * @HCI_DM_FIELD_GENERATOR: Allow to generate different kind of RF
+ *	technology. When using this command to anti-collision is done.
+ * @HCI_LOOPBACK: Allow to echo a command and test the Dh to CLF
+ *	connectivity.
+ * @HCI_DM_VDC_MEASUREMENT_VALUE: Allow to measure the field applied on the
+ *	CLF antenna. A value between 0 and 0x0f is returned. 0 is maximum.
+ * @HCI_DM_FWUPD_START: Allow to put CLF into firmware update mode. It is a
+ *	specific CLF command as there is no GPIO for this.
+ * @HCI_DM_FWUPD_END:  Allow to complete firmware update.
+ * @HCI_DM_VDC_VALUE_COMPARISON: Allow to compare the field applied on the
+ *	CLF antenna to a reference value.
+ * @MANUFACTURER_SPECIFIC: Allow to retrieve manufacturer specific data
+ *	received during a NCI_CORE_INIT_CMD.

+ *	driver.  (Initialized by comedi_alloc_subdevices().)
+ * @io_bits: Bit-mask indicating the channel directions for a DIO subdevice
+ *	with no more than 32 channels.  A '1' at a bit position indicates the
+ *	corresponding channel is configured as an output.  (Initialized by the

+ * @maxdata: If non-zero, this is the maximum raw data value of each channel.
+ *	If zero, the maximum data value is channel-specific.  (Initialized by

+ * @maxdata_list: If the maximum data value is channel-specific, this points
+ *	to an array of maximum data values indexed by channel index.
+ *	(Initialized by the low-level driver.)
+ * @range_table: If non-NULL, this points to a COMEDI range table for the

+ * @do_cmdtest: If the subdevice supports asynchronous acquisition commands,
+ *	this points to a handler used to check and possibly tweak a prospective
+ *	acquisition command without setting it up in hardware.  (Initialized by
+ *	the low-level driver.)
+ * @poll: If the subdevice supports asynchronous acquisition commands, this
+ *	is an optional pointer to a handler for the %COMEDI_POLL ioctl which
+ *	instructs the low-level driver to synchronize buffers.  (Initialized by

+ * @buf_change: If the subdevice supports asynchronous acquisition commands,
+ *	this is an optional pointer to a handler that is called when the data
+ *	buffer for handling asynchronous commands is allocated or reallocated.
+ *	(Initialized by the low-level driver if needed.)
+ * @munge: If the subdevice supports asynchronous acquisition commands and
+ *	uses DMA to transfer data from the hardware to the acquisition buffer,
+ *	this points to a function used to "munge" the data values from the
+ *	hardware into the format expected by COMEDI.  (Initialized by the

-2002/02/19 Fixed the two's complement conversion in pci9111_(hr_)ai_get_data.
-2002/02/18 Added external trigger support for analog input.
-
-TODO:
-
-	- Really test implemented functionality.
-	- Add support for the PCI-9111DG with a probe routine to identify
-	  the card type (perhaps with the help of the channel number readback
-	  of the A/D Data register).

-Status: works
-
-This driver supports AI, AO, DI and DO subdevices.
-AI subdevice supports cmd and insn interface,
-other subdevices support only insn interface.
-
-The PCI-1710 and PCI-1710HG have the same PCI device ID, so the
-driver cannot distinguish between them, as would be normal for a
-PCI driver.
-
-Configuration options:
-  [0] - PCI bus of device (optional)
-  [1] - PCI slot of device (optional)
-	If bus/slot is not specified, the first available PCI
-	device will be used.

-Driver: cb_pcidas
-Description: MeasurementComputing PCI-DAS series
-  with the AMCC S5933 PCI controller
-Author: Ivan Martinez <imr@oersted.dtu.dk>,
-  Frank Mori Hess <fmhess@users.sourceforge.net>
-Updated: 2003-3-11
-Devices: [Measurement Computing] PCI-DAS1602/16 (cb_pcidas),
-  PCI-DAS1602/16jr, PCI-DAS1602/12, PCI-DAS1200, PCI-DAS1200jr,
-  PCI-DAS1000, PCI-DAS1001, PCI_DAS1002
-
-Status:
-  There are many reports of the driver being used with most of the
-  supported cards. Despite no detailed log is maintained, it can
-  be said that the driver is quite tested and stable.
-
-  The boards may be autocalibrated using the comedi_calibrate
-  utility.
-
-Configuration options: not applicable, uses PCI auto config
-
-For commands, the scanned channels must be consecutive
-(i.e. 4-5-6-7, 2-3-4,...), and must all have the same
-range and aref.
-
-AI Triggering:
-   For start_src == TRIG_EXT, the A/D EXTERNAL TRIGGER IN (pin 45) is used.
-   For 1602 series, the start_arg is interpreted as follows:
-     start_arg == 0                   => gated trigger (level high)
-     start_arg == CR_INVERT           => gated trigger (level low)
-     start_arg == CR_EDGE             => Rising edge
-     start_arg == CR_EDGE | CR_INVERT => Falling edge
-   For the other boards the trigger will be done on rising edge

 /*
- * There exists a potential lock inversion deadlock scenario when using
- * Lustre on top of ZFS. This occurs between one of ZFS's
- * buf_hash_table.ht_lock's, and Lustre's lu_sites_guard lock. Essentially,
- * thread A will take the lu_sites_guard lock and sleep on the ht_lock,
- * while thread B will take the ht_lock and sleep on the lu_sites_guard
- * lock. Obviously neither thread will wake and drop their respective hold
- * on their lock.
+ * lu_cache_shrink_count returns the number of cached objects that are
+ * candidates to be freed by shrink_slab(). A counter, which tracks
+ * the number of items in the site's lru, is maintained in the per cpu
+ * stats of each site. The counter is incremented when an object is added
+ * to a site's lru and decremented when one is removed. The number of
+ * free-able objects is the sum of all per cpu counters for all sites.
  *
- * To prevent this from happening we must ensure the lu_sites_guard lock is
- * not taken while down this code path. ZFS reliably does not set the
- * __GFP_FS bit in its code paths, so this can be used to determine if it
- * is safe to take the lu_sites_guard lock.
- *
- * Ideally we should accurately return the remaining number of cached
- * objects without taking the  lu_sites_guard lock, but this is not
- * possible in the current implementation.
+ * Using a per cpu counter is a compromise solution to concurrent access:
+ * lu_object_put() can update the counter without locking the site and
+ * lu_cache_shrink_count can sum the counters without locking each
+ * ls_obj_hash bucket.

-Overview
-
-This document describes the driver set for Unisys Secure Partitioning (s-Par®).
+This document describes the driver set for Unisys Secure Partitioning
+(s-Par(R)).
 
 s-Par is firmware that provides hardware partitioning capabilities for
 splitting large-scale Intel x86 servers into multiple isolated
 partitions. s-Par provides a set of para-virtualized device drivers to
 allow guest partitions on the same server to share devices that would
-normally be unsharable; specifically, PCI network interfaces and host
-bus adapters that do not support shared access via SR-IOV. The shared
-device is owned and managed by a small, single-purpose service
-partition, which communicates with each guest partition sharing that
-device through an area of shared memory called a channel. Additional
-drivers provide support interfaces for communicating with s-Par
-services, logging and diagnostics, and accessing the Linux console
-from the s-Par user interface.
-
-The driver stack consists of a set of support modules, a set of bus
-modules, and a set of device driver modules. The support modules
-handle a number of common functions across each of the other
-drivers. The bus modules provide organization for the device driver
-modules, which provide the shared device functionality.
-
-These drivers are for the Unisys virtual PCI hardware model where the
-hypervisor need not intervene (other than normal interrupt handling)
-in the interactions between the client drivers and the virtual adapter
-firmware in the adapter service partition.
-
-Driver Descriptions
-
-Device Modules
-
-The modules in this section handle shared devices and the virtual
-buses required to support them. These modules use functions in and
-depend on the modules described in the support modules section.
-
-visorchipset
-
-The visorchipset module receives device creation and destruction
-events from the Command service partition of s-Par, as well as
-controlling registration of shared device drivers with the s-Par
-driver core. The events received are used to populate other s-Par
-modules with their assigned shared devices. Visorchipset is required
-for shared device drivers to function properly. Visorchipset also
-stores information for handling dump disk device creation during
-kdump.
-
-In operation, the visorchipset module processes device creation and
-destruction messages sent by s-Par's Command service partition through
-a channel. These messages result in creation (or destruction) of each
-virtual bus and virtual device. Each bus and device is also associated
-with a communication channel, which is used to communicate with one or
-more IO service partitions to perform device IO on behalf of the
-guest.
-
-virthba
-
-The virthba module provides access to a shared SCSI host bus adapter
-and one or more disk devices, by proxying SCSI commands between the
-guest and the service partition that owns the shared SCSI adapter,
-using a channel between the guest and the service partition. The disks
-that appear on the shared bus are defined by the s-Par configuration
-and enforced by the service partition, while the guest driver handles
-sending commands and handling responses. Each disk is shared as a
-whole to a guest. Sharing the bus adapter in this way provides
-resiliency; should the device encounter an error, only the service
+normally be unsharable, specifically:
+
+* visornic - network interface
+* visorhba - scsi disk adapter
+* visorinput - keyboard and mouse
+
+These drivers conform to the standard Linux bus/device model described
+within Documentation/driver-model/, and utilize a driver named visorbus to
+present the virtual busses involved. Drivers in the 'visor*' driver set are
+commonly referred to as "guest drivers" or "client drivers".  All drivers
+except visorbus expose a device of a specific usable class to the Linux guest
+environment (e.g., block, network, or input), and are collectively referred
+to as "function drivers".
+
+The back-end for each device is owned and managed by a small,
+single-purpose service partition in the s-Par firmware, which communicates
+with each guest partition sharing that device through an area of shared memory
+called a "channel". In s-Par nomenclature, the back-end is often referred to
+as the "service partition", "IO partition" (for virtual network and scsi disk
+devices), or "console partition" (for virtual keyboard and mouse devices).
+
+Each virtual device requires exactly 1 dedicated channel, which the guest
+driver and back-end use to communicate.  The hypervisor need not intervene
+(other than normal interrupt handling) in the interactions that occur across
+this channel.
+
+NOT covered in this document:
+
+* s-Par also supports sharing physical PCI adapters via SR-IOV, but
+  because this requires no specific support in the guest partitions, it will
+  not be discussed in this document.  Shared SR-IOV devices should be used
+  wherever possible for highest performance.
+
+* Because the s-Par back-end provides a standard EFI framebuffer to each
+  guest, the already-existing efifb Linux driver is used to provide guest
+  video access. Thus, the only s-Par-unique support that is necessary to
+  provide a guest graphics console are for keyboard and mouse (via visorinput).
+
+
+2. Driver Descriptions
+----------------------
+
+2.1. visorbus
+-------------
+
+2.1.1. Overview
+---------------
+
+The visorbus driver handles the virtual busses on which all of the virtual
+devices reside. It provides a registration function named
+visorbus_register_visor_driver() that is called by each of the function
+drivers at initialization time, which the function driver uses to tell
+visorbus about the device classes (via specifying a list of device type
+GUIDs) it wants to handle. For use by function drivers, visorbus provides
+implementation for struct visor_driver and struct visor_device, as well
+as utility functions for communicating with the back-end.
+
+visorbus is associated with ACPI id "PNP0A07" in modules.alias, so if built
+as a module it will typically be loaded automatically via standard udev or
+systemd (God help us) configurations.
+
+visorbus can similarly force auto-loading of function drivers for virtual
+devices it discovers, as it includes a MODALIAS environment variable of this
+form in the hotplug uevent environment when each virtual device is
+discovered:
+
+    visorbus:<device type GUID>
+
+visorbus notifies each function driver when a device of its registered class
+arrives and departs, by calling the function driver's probe() and remove()
+methods.
+
+The actual struct device objects that correspond to each virtual bus and
+each virtual device are created and owned by visorbus.  These device objects
+are created in response to messages from the s-Par back-end received on a
+special control channel called the "controlvm channel" (each guest partition
+has access to exactly 1 controlvm channel), and have a lifetime that is
+independent of the function drivers that control them.
+
+2.1.2. "struct visor device" Function Driver Interfaces
+-------------------------------------------------------
+
+The interface between visorbus and its function drivers is defined in
+visorbus.h, and described below.
+
+When a visor function driver loads, it calls visorbus_register_visor_driver()
+to register itself with visorbus. The significant information passed in this
+exchange is as follows:
+
+* the GUID(s) of the channel type(s) that are handled by this driver, as
+  well as a "friendly name" identifying each (this will be published under
+  /sys/devices/visorbus<x>/dev<y>)
+
+* the addresses of callback functions to be called whenever a virtual
+  device/channel with the appropriate channel-type GUID(s) appears or
+  disappears
+
+* the address of a "channel_interrupt" function, which will be automatically
+  called at specific intervals to enable the driver to poll the device
+  channel for activity
+
+The following functions implemented within each function driver will be
+called automatically by the visorbus driver at appropriate times:
+
+* The probe() function notifies about the creation of each new virtual
+  device/channel instance.
+
+* The remove() function notifies about the destruction of a virtual
+  device/channel instance.
+
+* The channel_interrupt() function is called at frequent intervals to
+  give the function driver an opportunity to poll the virtual device channel
+  for requests.  Information is passed to this function to enable the
+  function driver to use the visorchannel_signalinsert() and
+  visorchannel_signalremove() functions to respond to and initiate activity
+  over the channel.  (Note that since it is the visorbus driver that
+  determines when this is called, it is very easy to switch to
+  interrupt-driven mechanisms when available for particular virtual device
+  types.)
+
+* The pause() function is called should it ever be necessary to direct the
+  function driver to temporarily stop accessing the device channel.  An
+  example of when this is needed is when the service partition implementing
+  the back-end of the virtual device needs to be recovered.  After a
+  successful return of pause(), the function driver must not access the
+  device channel until a subsequent resume() occurs.
+
+* The resume() function is the "book-end" to pause(), and is described above.
+
+If/when a function driver creates a Linux device (that needs to be accessed
+from usermode), it calls visorbus_registerdevnode(), passing the major and
+minor number of the device.  (Of course not all function drivers will need
+to do this.)  This simply creates the appropriate "devmajorminor" sysfs entry
+described below, so that a hotplug script can use it to create a device node.
+
+2.1.3. sysfs Advertised Information
+-----------------------------------
+
+Because visorbus is a standard Linux bus driver in the model described in
+Documentation/driver-model/, the hierarchy of s-Par virtual devices is
+published in the sysfs tree beneath /bus/visorbus/, e.g.,
+/sys/bus/visorbus/devices/ might look like:
+
+    vbus1:dev1 -> ../../../devices/visorbus1/vbus1:dev1
+    vbus1:dev2 -> ../../../devices/visorbus1/vbus1:dev2
+    vbus1:dev3 -> ../../../devices/visorbus1/vbus1:dev3
+    vbus2:dev0 -> ../../../devices/visorbus2/vbus2:dev0
+    vbus2:dev1 -> ../../../devices/visorbus2/vbus2:dev1
+    vbus2:dev2 -> ../../../devices/visorbus2/vbus2:dev2
+    visorbus1 -> ../../../devices/visorbus1
+    visorbus2 -> ../../../devices/visorbus2
+
+visor_device notes:
+
+* Each visorbus<n> entry denotes the existence of a struct visor_device
+  denoting virtual bus #<n>.  A unique s-Par channel exists for each such
+  virtual bus.
+
+* Virtual bus numbers uniquely identify s-Par back-end service partitions.
+  In this example, bus 1 corresponds to the s-Par console partition
+  (controls keyboard, video, and mouse), whereas bus 2 corresponds to the
+  s-Par IO partition (controls network and disk).
+
+* Each vbus<x>:dev<y> entry denotes the existence of a struct visor_device
+  denoting virtual device #<y> outboard of virtual bus #<x>.  A unique s-Par
+  channel exists for each such virtual device.
+
+* If a function driver has loaded and claimed a particular device, the
+  bus/visorbus/devices/vbus<x>:dev<y>/driver symlink will indicate that
+  function driver.
+
+Every active visorbus device will have a sysfs subtree under:
+
+    /sys/devices/visorbus<x>/vbus<x>:dev<y>/
+
+The following files exist under /sys/devices/visorbus<x>/vbus<x>:dev<y>:
+
+    subsystem                 link to sysfs tree that describes the
+                              visorbus bus type; e.g.:

+                                  ../../../bus/visorbus/drivers/visorhba
+                              Note that this "driver" link will not exist
+                              if the appropriate function driver has not
+                              been loaded yet.
+
+    devmajorminor
+
+        <devname>             if applicable, each file here identifies (via
+        ...                   its file contents) the
+                              "<major>:<minor>" needed for a device node to
+                              enable access from usermode.  There is exactly
+                              one file here for each different device node
+                              that can be accessed (from usermode).  Note
+                              that this info is provided by a particular
+                              function driver, so these will not exist

+                              will return an empty string until AFTER the
+                              appropriate function driver controlling this

+2.2. visorhba
+-------------
+
+The visorhba driver registers with visorbus as the function driver to
+handle virtual scsi disk devices, specified using the
+SPAR_VHBA_CHANNEL_PROTOCOL_UUID type in the visorbus_register_visor_driver()
+call. visorhba uses scsi_add_host() to expose a Linux block device
+(e.g., /sys/block/) in the guest environment for each s-Par virtual device.
+
+visorhba provides access to a shared SCSI host bus adapter and one or more
+disk devices, by proxying SCSI commands between the guest and the service
+partition that owns the shared SCSI adapter, using a channel between the
+guest and the service partition. The disks that appear on the shared bus
+are defined by the s-Par configuration and enforced by the service partition,
+while the guest driver handles sending commands and handling responses. Each
+disk is shared as a whole to a guest. Sharing the bus adapter in this way
+provides resiliency; should the device encounter an error, only the service
 partition is rebooted, and the device is reinitialized. This allows
 guests to continue running and to recover from the error.

+for example, visornic is not technically required.
 
-The drivers required to boot a Linux guest are visorchipset, visorbus,
-visorvideoclient, visorconinclient, visoruislib, visorchannelstub,
-visorchannel, and visorutil. The other drivers are required by the
-product configurations that are currently being marketed.
+visorinput is only required for a Linux guest running under s-Par if you
+require graphics-mode access to your guest console.

-		-visordiag
-		-virtnic
-		-visornoop
-		-visorserial
-		-visorvideoclient
-		-visorconinclient

-		
+	- enhance visornic to use channel_interrupt() hook instead of a
+	  kernel thread
+	- enhance visorhba to use channel_interrupt() hook instead of a
+	  kernel thread
+	- teach visorbus to handle virtual interrupts triggered by s-Par
+	  back-end, and call function driver's channel_interrupt() function
+	  when they occur
+	- enhance debugfs interfaces (e.g., per device, etc.)
+	- upgrade/remove deprecated workqueue operations

- * The default hierarchy is the v2 interface of cgroup and this function

- * cases where a subsystem should behave differnetly depending on the
- * interface version.
- *
- * The set of behaviors which change on the default hierarchy are still
- * being determined and the mount option is prefixed with __DEVEL__.
- *
- * List of changed behaviors:
- *
- * - Mount options "noprefix", "xattr", "clone_children", "release_agent"
- *   and "name" are disallowed.
- *
- * - When mounting an existing superblock, mount options should match.
- *
- * - Remount is disallowed.
- *
- * - rename(2) is disallowed.
- *
- * - "tasks" is removed.  Everything should be at process granularity.  Use
- *   "cgroup.procs" instead.
- *
- * - "cgroup.procs" is not sorted.  pids will be unique unless they got
- *   recycled inbetween reads.
- *
- * - "release_agent" and "notify_on_release" are removed.  Replacement
- *   notification mechanism will be implemented.
- *
- * - "cgroup.clone_children" is removed.
- *
- * - "cgroup.subtree_populated" is available.  Its value is 0 if the cgroup
- *   and its descendants contain no task; otherwise, 1.  The file also
- *   generates kernfs notification which can be monitored through poll and
- *   [di]notify when the value of the file changes.
- *
- * - cpuset: tasks will be kept in empty cpusets when hotplug happens and
- *   take masks of ancestors with non-empty cpus/mems, instead of being
- *   moved to an ancestor.
- *
- * - cpuset: a task can be moved into an empty cpuset, and again it takes
- *   masks of ancestors.
- *
- * - memcg: use_hierarchy is on by default and the cgroup file for the flag
- *   is not created.
- *
- * - blkcg: blk-throttle becomes properly hierarchical.

+ * event type. The argument must be of type "struct input_mask" and
+ * specifies the event type to query, the address of the receive buffer and
+ * the size of the receive buffer.
+ *
+ * The event mask is a per-client mask that specifies which events are
+ * forwarded to the client. Each event code is represented by a single bit
+ * in the event mask. If the bit is set, the event is passed to the client
+ * normally. Otherwise, the event is filtered and will never be queued on
+ * the client's receive buffer.
+ *
+ * Event masks do not affect global state of the input device. They only
+ * affect the file descriptor they are applied to.
+ *
+ * The default event mask for a client has all bits set, i.e. all events
+ * are forwarded to the client. If the kernel is queried for an unknown
+ * event type or if the receive buffer is larger than the number of
+ * event codes known to the kernel, the kernel returns all zeroes for those
+ * codes.
+ *
+ * At maximum, codes_size bytes are copied.

+ * i.e. to add new instructions to the test, edit insn-x86-dat-src.c, run the
+ * gen-insn-x86-dat.sh script, make perf, and then run the test.
+ *
+ * If the test passes %0 is returned, otherwise %-1 is returned.  Use the

 # An example of using the database is provided by the script
 # call-graph-from-postgresql.py.  Refer to that script for details.
+#
+# Tables:
+#
+#	The tables largely correspond to perf tools' data structures.  They are largely self-explanatory.
+#
+#	samples
+#
+#		'samples' is the main table. It represents what instruction was executing at a point in time
+#		when something (a selected event) happened.  The memory address is the instruction pointer or 'ip'.
+#
+#	calls
+#
+#		'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
+#		'calls' is only created when the 'calls' option to this script is specified.
+#
+#	call_paths
+#
+#		'call_paths' represents all the call stacks.  Each 'call' has an associated record in 'call_paths'.
+#		'calls_paths' is only created when the 'calls' option to this script is specified.
+#
+#	branch_types
+#
+#		'branch_types' provides descriptions for each type of branch.
+#
+#	comm_threads
+#
+#		'comm_threads' shows how 'comms' relates to 'threads'.
+#
+#	comms
+#
+#		'comms' contains a record for each 'comm' - the name given to the executable that is running.
+#
+#	dsos
+#
+#		'dsos' contains a record for each executable file or library.
+#
+#	machines
+#
+#		'machines' can be used to distinguish virtual machines if virtualization is supported.
+#
+#	selected_events
+#
+#		'selected_events' contains a record for each kind of event that has been sampled.
+#
+#	symbols
+#
+#		'symbols' contains a record for each symbol.  Only symbols that have samples are present.
+#
+#	threads
+#
+#		'threads' contains a record for each thread.
+#
+# Views:
+#
+#	Most of the tables have views for more friendly display.  The views are:
+#
+#		calls_view
+#		call_paths_view
+#		comm_threads_view
+#		dsos_view
+#		machines_view
+#		samples_view
+#		symbols_view
+#		threads_view
+#
+# More examples of browsing the database with psql:
+#   Note that some of the examples are not the most optimal SQL query.
+#   Note that call information is only available if the script's 'calls' option has been used.
+#
+#	Top 10 function calls (not aggregated by symbol):
+#
+#		SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
+#

+#			SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
+#			FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
+#
+#		Note that the branch count gives a rough estimation of cpu usage, so functions
+#		that took a long time but have a relatively low branch count must have spent time
+#		waiting.
+#
+#	Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
+#
+#		SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
+#
+#	Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
+#
+#		SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
+#
+#	Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
+#
+#		SELECT * FROM calls_view WHERE parent_call_path_id = 254;
+#
+#	Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
+#
+#		SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
+#
+#	Show transactions:
+#
+#		SELECT * FROM samples_view WHERE event = 'transactions';
+#
+#		Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
+#		Transaction aborts have branch_type_name 'transaction abort'
+#

+#
+#		SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
