+Unfortunately, this thread can use a lot of CPU depending on the

 The driver supports a hot add and remove of interfaces.  This way,
 interfaces can be added or removed after the kernel is up and running.

+		Samsung ARM Linux Overview
+		==========================
+
+Introduction
+------------
+
+  The Samsung range of ARM SoCs spans many similar devices, from the initial
+  ARM9 through to the newest ARM cores. This document shows an overview of
+  the current kernel support, how to use it and where to find the code
+  that supports this.
+
+  The currently supported SoCs are:
+
+  - S3C24XX: See Documentation/arm/Samsung-S3C24XX/Overview.txt for full list
+  - S3C64XX: S3C6400 and S3C6410
+  - S5PC6440
+
+  S5PC100 and S5PC110 support is currently being merged
+
+
+S3C24XX Systems
+---------------
+
+  There is still documentation in Documnetation/arm/Samsung-S3C24XX/ which
+  deals with the architecture and drivers specific to these devices.
+
+  See Documentation/arm/Samsung-S3C24XX/Overview.txt for more information
+  on the implementation details and specific support.
+
+
+Configuration
+-------------
+
+  A number of configurations are supplied, as there is no current way of
+  unifying all the SoCs into one kernel.
+
+  s5p6440_defconfig - S5P6440 specific default configuration
+  s5pc100_defconfig - S5PC100 specific default configuration
+
+
+Layout
+------
+
+  The directory layout is currently being restructured, and consists of
+  several platform directories and then the machine specific directories
+  of the CPUs being built for.
+
+  plat-samsung provides the base for all the implementations, and is the
+  last in the line of include directories that are processed for the build
+  specific information. It contains the base clock, GPIO and device definitions
+  to get the system running.
+
+  plat-s3c is the s3c24xx/s3c64xx platform directory, although it is currently
+  involved in other builds this will be phased out once the relevant code is
+  moved elsewhere.
+
+  plat-s3c24xx is for s3c24xx specific builds, see the S3C24XX docs.
+
+  plat-s3c64xx is for the s3c64xx specific bits, see the S3C24XX docs.
+
+  plat-s5p is for s5p specific builds, more to be added.

+There is mechanism which allows to get notifications about changing

+Users can move charges associated with a task along with task migration, that
+is, uncharge task's pages from the old cgroup and charge them to the new cgroup.
+This feature is not supported in !CONFIG_MMU environments because of lack of
+page tables.
+
+8.1 Interface
+
+This feature is disabled by default. It can be enabled(and disabled again) by
+writing to memory.move_charge_at_immigrate of the destination cgroup.
+
+If you want to enable it:
+
+# echo (some positive value) > memory.move_charge_at_immigrate
+
+Note: Each bits of move_charge_at_immigrate has its own meaning about what type
+      of charges should be moved. See 8.2 for details.
+Note: Charges are moved only when you move mm->owner, IOW, a leader of a thread
+      group.
+Note: If we cannot find enough space for the task in the destination cgroup, we
+      try to make space by reclaiming memory. Task migration may fail if we
+      cannot make enough space.
+Note: It can take several seconds if you move charges in giga bytes order.
+
+And if you want disable it again:
+
+# echo 0 > memory.move_charge_at_immigrate
+
+8.2 Type of charges which can be move
+
+Each bits of move_charge_at_immigrate has its own meaning about what type of
+charges should be moved.
+
+  bit | what type of charges would be moved ?

+      | Those pages and swaps must be used only by the target task. You must
+      | enable Swap Extension(see 2.4) to enable move of swap charges.
+
+Note: Those pages and swaps must be charged to the old cgroup.
+Note: More type of pages(e.g. file cache, shmem,) will be supported by other
+      bits in future.
+
+8.3 TODO
+
+- Add support for other types of pages(e.g. file cache, shmem, etc.).
+- Implement madvise(2) to let users decide the vma to be moved or not to be
+  moved.
+- All of moving charge operations are done under cgroup_mutex. It's not good
+  behavior to hold the mutex too long, so we may need some trick.
+
+9. Memory thresholds
+
+Memory controler implements memory thresholds using cgroups notification
+API (see cgroups.txt). It allows to register multiple memory and memsw
+thresholds and gets notifications when it crosses.
+
+To register a threshold application need:
+ - create an eventfd using eventfd(2);
+ - open memory.usage_in_bytes or memory.memsw.usage_in_bytes;
+ - write string like "<event_fd> <memory.usage_in_bytes> <threshold>" to
+   cgroup.event_control.
+
+Application will be notified through eventfd when memory usage crosses
+threshold in any direction.
+
+It's applicable for root and non-root cgroup.
+
+10. TODO
 
 1. Add support for accounting huge pages (as a separate controller)
 2. Make per-cgroup scanner reclaim not-shared pages first

+			       ================
+
+By: David Howells <dhowells@redhat.com>
+    Paul E. McKenney <paulmck@linux.vnet.ibm.com>
+
+
+Linux provides a number of features that can be used to implement circular
+buffering.  There are two sets of such features:
+
+ (1) Convenience functions for determining information about power-of-2 sized
+     buffers.
+
+ (2) Memory barriers for when the producer and the consumer of objects in the
+     buffer don't want to share a lock.
+
+To use these facilities, as discussed below, there needs to be just one
+producer and just one consumer.  It is possible to handle multiple producers by
+serialising them, and to handle multiple consumers by serialising them.
+
+
+Contents:
+
+ (*) What is a circular buffer?
+
+ (*) Measuring power-of-2 buffers.
+
+ (*) Using memory barriers with circular buffers.
+     - The producer.
+     - The consumer.
+
+
+==========================
+WHAT IS A CIRCULAR BUFFER?
+==========================
+
+First of all, what is a circular buffer?  A circular buffer is a buffer of
+fixed, finite size into which there are two indices:
+
+ (1) A 'head' index - the point at which the producer inserts items into the
+     buffer.
+
+ (2) A 'tail' index - the point at which the consumer finds the next item in
+     the buffer.
+
+Typically when the tail pointer is equal to the head pointer, the buffer is
+empty; and the buffer is full when the head pointer is one less than the tail
+pointer.
+
+The head index is incremented when items are added, and the tail index when
+items are removed.  The tail index should never jump the head index, and both
+indices should be wrapped to 0 when they reach the end of the buffer, thus
+allowing an infinite amount of data to flow through the buffer.
+
+Typically, items will all be of the same unit size, but this isn't strictly
+required to use the techniques below.  The indices can be increased by more
+than 1 if multiple items or variable-sized items are to be included in the
+buffer, provided that neither index overtakes the other.  The implementer must
+be careful, however, as a region more than one unit in size may wrap the end of
+the buffer and be broken into two segments.
+
+
+============================
+MEASURING POWER-OF-2 BUFFERS
+============================
+
+Calculation of the occupancy or the remaining capacity of an arbitrarily sized
+circular buffer would normally be a slow operation, requiring the use of a
+modulus (divide) instruction.  However, if the buffer is of a power-of-2 size,
+then a much quicker bitwise-AND instruction can be used instead.
+
+Linux provides a set of macros for handling power-of-2 circular buffers.  These
+can be made use of by:
+
+	#include <linux/circ_buf.h>
+
+The macros are:
+
+ (*) Measure the remaining capacity of a buffer:
+
+	CIRC_SPACE(head_index, tail_index, buffer_size);
+
+     This returns the amount of space left in the buffer[1] into which items
+     can be inserted.
+
+
+ (*) Measure the maximum consecutive immediate space in a buffer:
+
+	CIRC_SPACE_TO_END(head_index, tail_index, buffer_size);
+
+     This returns the amount of consecutive space left in the buffer[1] into
+     which items can be immediately inserted without having to wrap back to the
+     beginning of the buffer.
+
+
+ (*) Measure the occupancy of a buffer:
+
+	CIRC_CNT(head_index, tail_index, buffer_size);
+
+     This returns the number of items currently occupying a buffer[2].
+
+
+ (*) Measure the non-wrapping occupancy of a buffer:
+
+	CIRC_CNT_TO_END(head_index, tail_index, buffer_size);
+
+     This returns the number of consecutive items[2] that can be extracted from
+     the buffer without having to wrap back to the beginning of the buffer.
+
+
+Each of these macros will nominally return a value between 0 and buffer_size-1,
+however:
+
+ [1] CIRC_SPACE*() are intended to be used in the producer.  To the producer
+     they will return a lower bound as the producer controls the head index,
+     but the consumer may still be depleting the buffer on another CPU and
+     moving the tail index.
+
+     To the consumer it will show an upper bound as the producer may be busy
+     depleting the space.
+
+ [2] CIRC_CNT*() are intended to be used in the consumer.  To the consumer they
+     will return a lower bound as the consumer controls the tail index, but the
+     producer may still be filling the buffer on another CPU and moving the
+     head index.
+
+     To the producer it will show an upper bound as the consumer may be busy
+     emptying the buffer.
+
+ [3] To a third party, the order in which the writes to the indices by the
+     producer and consumer become visible cannot be guaranteed as they are
+     independent and may be made on different CPUs - so the result in such a
+     situation will merely be a guess, and may even be negative.
+
+
+===========================================
+USING MEMORY BARRIERS WITH CIRCULAR BUFFERS
+===========================================
+
+By using memory barriers in conjunction with circular buffers, you can avoid
+the need to:
+
+ (1) use a single lock to govern access to both ends of the buffer, thus
+     allowing the buffer to be filled and emptied at the same time; and
+
+ (2) use atomic counter operations.
+
+There are two sides to this: the producer that fills the buffer, and the
+consumer that empties it.  Only one thing should be filling a buffer at any one
+time, and only one thing should be emptying a buffer at any one time, but the
+two sides can operate simultaneously.
+
+
+THE PRODUCER
+------------
+
+The producer will look something like this:
+
+	spin_lock(&producer_lock);
+
+	unsigned long head = buffer->head;
+	unsigned long tail = ACCESS_ONCE(buffer->tail);
+
+	if (CIRC_SPACE(head, tail, buffer->size) >= 1) {
+		/* insert one item into the buffer */
+		struct item *item = buffer[head];
+
+		produce_item(item);
+
+		smp_wmb(); /* commit the item before incrementing the head */
+
+		buffer->head = (head + 1) & (buffer->size - 1);
+
+		/* wake_up() will make sure that the head is committed before
+		 * waking anyone up */
+		wake_up(consumer);
+	}
+
+	spin_unlock(&producer_lock);
+
+This will instruct the CPU that the contents of the new item must be written
+before the head index makes it available to the consumer and then instructs the
+CPU that the revised head index must be written before the consumer is woken.
+
+Note that wake_up() doesn't have to be the exact mechanism used, but whatever
+is used must guarantee a (write) memory barrier between the update of the head
+index and the change of state of the consumer, if a change of state occurs.
+
+
+THE CONSUMER
+------------
+
+The consumer will look something like this:
+
+	spin_lock(&consumer_lock);
+
+	unsigned long head = ACCESS_ONCE(buffer->head);
+	unsigned long tail = buffer->tail;
+
+	if (CIRC_CNT(head, tail, buffer->size) >= 1) {
+		/* read index before reading contents at that index */
+		smp_read_barrier_depends();
+
+		/* extract one item from the buffer */
+		struct item *item = buffer[tail];
+
+		consume_item(item);
+
+		smp_mb(); /* finish reading descriptor before incrementing tail */
+
+		buffer->tail = (tail + 1) & (buffer->size - 1);
+	}
+
+	spin_unlock(&consumer_lock);
+
+This will instruct the CPU to make sure the index is up to date before reading
+the new item, and then it shall make sure the CPU has finished reading the item
+before it writes the new tail pointer, which will erase the item.
+
+
+Note the use of ACCESS_ONCE() in both algorithms to read the opposition index.
+This prevents the compiler from discarding and reloading its cached value -
+which some compilers will do across smp_read_barrier_depends().  This isn't
+strictly needed if you can be sure that the opposition index will _only_ be
+used the once.

+Ceph Distributed File System
+============================
+
+Ceph is a distributed network file system designed to provide good
+performance, reliability, and scalability.
+
+Basic features include:
+
+ * POSIX semantics
+ * Seamless scaling from 1 to many thousands of nodes
+ * High availability and reliability.  No single point of failure.
+ * N-way replication of data across storage nodes
+ * Fast recovery from node failures
+ * Automatic rebalancing of data on node addition/removal
+ * Easy deployment: most FS components are userspace daemons
+
+Also,
+ * Flexible snapshots (on any directory)
+ * Recursive accounting (nested files, directories, bytes)
+
+In contrast to cluster filesystems like GFS, OCFS2, and GPFS that rely
+on symmetric access by all clients to shared block devices, Ceph
+separates data and metadata management into independent server
+clusters, similar to Lustre.  Unlike Lustre, however, metadata and
+storage nodes run entirely as user space daemons.  Storage nodes
+utilize btrfs to store data objects, leveraging its advanced features
+(checksumming, metadata replication, etc.).  File data is striped
+across storage nodes in large chunks to distribute workload and
+facilitate high throughputs.  When storage nodes fail, data is
+re-replicated in a distributed fashion by the storage nodes themselves
+(with some minimal coordination from a cluster monitor), making the
+system extremely efficient and scalable.
+
+Metadata servers effectively form a large, consistent, distributed
+in-memory cache above the file namespace that is extremely scalable,
+dynamically redistributes metadata in response to workload changes,
+and can tolerate arbitrary (well, non-Byzantine) node failures.  The
+metadata server takes a somewhat unconventional approach to metadata
+storage to significantly improve performance for common workloads.  In
+particular, inodes with only a single link are embedded in
+directories, allowing entire directories of dentries and inodes to be
+loaded into its cache with a single I/O operation.  The contents of
+extremely large directories can be fragmented and managed by
+independent metadata servers, allowing scalable concurrent access.
+
+The system offers automatic data rebalancing/migration when scaling
+from a small cluster of just a few nodes to many hundreds, without
+requiring an administrator carve the data set into static volumes or
+go through the tedious process of migrating data between servers.
+When the file system approaches full, new nodes can be easily added
+and things will "just work."
+
+Ceph includes flexible snapshot mechanism that allows a user to create
+a snapshot on any subdirectory (and its nested contents) in the
+system.  Snapshot creation and deletion are as simple as 'mkdir
+.snap/foo' and 'rmdir .snap/foo'.
+
+Ceph also provides some recursive accounting on directories for nested
+files and bytes.  That is, a 'getfattr -d foo' on any directory in the
+system will reveal the total number of nested regular files and
+subdirectories, and a summation of all nested file sizes.  This makes
+the identification of large disk space consumers relatively quick, as
+no 'du' or similar recursive scan of the file system is required.
+
+
+Mount Syntax
+============
+
+The basic mount syntax is:
+
+ # mount -t ceph monip[:port][,monip2[:port]...]:/[subdir] mnt
+
+You only need to specify a single monitor, as the client will get the
+full list when it connects.  (However, if the monitor you specify
+happens to be down, the mount won't succeed.)  The port can be left
+off if the monitor is using the default.  So if the monitor is at
+1.2.3.4,
+
+ # mount -t ceph 1.2.3.4:/ /mnt/ceph
+
+is sufficient.  If /sbin/mount.ceph is installed, a hostname can be
+used instead of an IP address.
+
+
+
+Mount Options
+=============
+
+  ip=A.B.C.D[:N]
+	Specify the IP and/or port the client should bind to locally.
+	There is normally not much reason to do this.  If the IP is not
+	specified, the client's IP address is determined by looking at the
+	address it's connection to the monitor originates from.
+
+  wsize=X
+	Specify the maximum write size in bytes.  By default there is no
+	maximum.  Ceph will normally size writes based on the file stripe
+	size.
+
+  rsize=X
+	Specify the maximum readahead.
+
+  mount_timeout=X
+	Specify the timeout value for mount (in seconds), in the case
+	of a non-responsive Ceph file system.  The default is 30
+	seconds.
+
+  rbytes
+	When stat() is called on a directory, set st_size to 'rbytes',
+	the summation of file sizes over all files nested beneath that
+	directory.  This is the default.

+If you have a struct uio_map structure, finding its embedded kobject is
 just a matter of using the kobj member.  Code that works with kobjects will
 often have the opposite problem, however: given a struct kobject pointer,
 what is the pointer to the containing structure?  You must avoid tricks
 (such as assuming that the kobject is at the beginning of the structure)
 and, instead, use the container_of() macro, found in <linux/kernel.h>:

+The return value from container_of() is a pointer to the corresponding

+*containing* uio_map structure with:
+
+    struct uio_map *u_map = container_of(kp, struct uio_map, kobj);
+
+For convenience, programmers often define a simple macro for "back-casting"

+       STMicroelectronics 10/100/1000 Synopsys Ethernet driver
+
+Copyright (C) 2007-2010  STMicroelectronics Ltd
+Author: Giuseppe Cavallaro <peppe.cavallaro@st.com>
+
+This is the driver for the MAC 10/100/1000 on-chip Ethernet controllers
+(Synopsys IP blocks); it has been fully tested on STLinux platforms.
+
+Currently this network device driver is for all STM embedded MAC/GMAC
+(7xxx SoCs).
+
+DWC Ether MAC 10/100/1000 Universal version 3.41a and DWC Ether MAC 10/100
+Universal version 4.0 have been used for developing the first code
+implementation.
+
+Please, for more information also visit: www.stlinux.com
+
+1) Kernel Configuration
+The kernel configuration option is STMMAC_ETH:
+ Device Drivers ---> Network device support ---> Ethernet (1000 Mbit) --->
+ STMicroelectronics 10/100/1000 Ethernet driver (STMMAC_ETH)
+
+2) Driver parameters list:
+	debug: message level (0: no output, 16: all);
+	phyaddr: to manually provide the physical address to the PHY device;
+	dma_rxsize: DMA rx ring size;
+	dma_txsize: DMA tx ring size;
+	buf_sz: DMA buffer size;
+	tc: control the HW FIFO threshold;
+	tx_coe: Enable/Disable Tx Checksum Offload engine;
+	watchdog: transmit timeout (in milliseconds);
+	flow_ctrl: Flow control ability [on/off];
+	pause: Flow Control Pause Time;
+	tmrate: timer period (only if timer optimisation is configured).
+
+3) Command line options
+Driver parameters can be also passed in command line by using:
+	stmmaceth=dma_rxsize:128,dma_txsize:512
+
+4) Driver information and notes
+
+4.1) Transmit process
+The xmit method is invoked when the kernel needs to transmit a packet; it sets
+the descriptors in the ring and informs the DMA engine that there is a packet
+ready to be transmitted.
+Once the controller has finished transmitting the packet, an interrupt is
+triggered; So the driver will be able to release the socket buffers.
+By default, the driver sets the NETIF_F_SG bit in the features field of the
+net_device structure enabling the scatter/gather feature.
+
+4.2) Receive process
+When one or more packets are received, an interrupt happens. The interrupts
+are not queued so the driver has to scan all the descriptors in the ring during
+the receive process.
+This is based on NAPI so the interrupt handler signals only if there is work to be
+done, and it exits.
+Then the poll method will be scheduled at some future point.
+The incoming packets are stored, by the DMA, in a list of pre-allocated socket
+buffers in order to avoid the memcpy (Zero-copy).
+
+4.3) Timer-Driver Interrupt
+Instead of having the device that asynchronously notifies the frame receptions, the
+driver configures a timer to generate an interrupt at regular intervals.
+Based on the granularity of the timer, the frames that are received by the device
+will experience different levels of latency. Some NICs have dedicated timer
+device to perform this task. STMMAC can use either the RTC device or the TMU
+channel 2  on STLinux platforms.
+The timers frequency can be passed to the driver as parameter; when change it,
+take care of both hardware capability and network stability/performance impact.
+Several performance tests on STM platforms showed this optimisation allows to spare
+the CPU while having the maximum throughput.
+
+4.4) WOL
+Wake up on Lan feature through Magic Frame is only supported for the GMAC
+core.
+
+4.5) DMA descriptors
+Driver handles both normal and enhanced descriptors. The latter has been only
+tested on DWC Ether MAC 10/100/1000 Universal version 3.41a.
+
+4.6) Ethtool support
+Ethtool is supported. Driver statistics and internal errors can be taken using:
+ethtool -S ethX command. It is possible to dump registers etc.
+
+4.7) Jumbo and Segmentation Offloading
+Jumbo frames are supported and tested for the GMAC.
+The GSO has been also added but it's performed in software.
+LRO is not supported.
+
+4.8) Physical
+The driver is compatible with PAL to work with PHY and GPHY devices.
+
+4.9) Platform information
+Several information came from the platform; please refer to the
+driver's Header file in include/linux directory.
+

+        int bus_id;
+        int pbl;

+#ifdef CONFIG_STM_DRIVERS
+        struct stm_pad_config *pad_config;
+#endif
+        void *bsp_priv;
+};
+
+Where:
+- pbl (Programmable Burst Length) is maximum number of
+  beats to be transferred in one DMA transaction.
+  GMAC also enables the 4xPBL by default.
+- fix_mac_speed and bus_setup are used to configure internal target
+  registers (on STM platforms);
+- has_gmac: GMAC core is on board (get it at run-time in the next step);
+- bus_id: bus identifier.

+struct plat_stmmacphy_data {
+        int bus_id;
+        int phy_addr;
+        unsigned int phy_mask;
+        int interface;
+        int (*phy_reset)(void *priv);
+        void *priv;
+};
+
+Where:
+- bus_id: bus identifier;
+- phy_addr: physical address used for the attached phy device;
+            set it to -1 to get it at run-time;
+- interface: physical MII interface mode;
+- phy_reset: hook to reset HW function.
+
+TODO:
+- Continue to make the driver more generic and suitable for other Synopsys
+  Ethernet controllers used on other architectures (i.e. ARM).
+- 10G controllers are not supported.
+- MAC uses Normal descriptors and GMAC uses enhanced ones.
+  This is a limit that should be reviewed. MAC could want to
+  use the enhanced structure.
+- Checksumming: Rx/Tx csum is done in HW in case of GMAC only.
+- Review the timer optimisation code to use an embedded device that seems to be
+  available in new chip generations.

 DEVICE IMPLEMENTATION
 
 A driver which supports hardware time stamping must support the
-SIOCSHWTSTAMP ioctl. Time stamps for received packets must be stored
-in the skb with skb_hwtstamp_set().
+SIOCSHWTSTAMP ioctl and update the supplied struct hwtstamp_config with
+the actual values as described in the section on SIOCSHWTSTAMP.
+
+Time stamps for received packets must be stored in the skb. To get a pointer
+to the shared time stamp structure of the skb call skb_hwtstamps(). Then
+set the time stamps in the structure:
+
+struct skb_shared_hwtstamps {
+	/* hardware time stamp transformed into duration
+	 * since arbitrary point in time
+	 */
+	ktime_t	hwtstamp;
+	ktime_t	syststamp; /* hwtstamp transformed to system time base */
+};
 
 Time stamps for outgoing packets are to be generated as follows:
-- In hard_start_xmit(), check if skb_hwtstamp_check_tx_hardware()
-  returns non-zero. If yes, then the driver is expected
-  to do hardware time stamping.
+- In hard_start_xmit(), check if skb_tx(skb)->hardware is set no-zero.
+  If yes, then the driver is expected to do hardware time stamping.
 - If this is possible for the skb and requested, then declare
-  that the driver is doing the time stamping by calling
-  skb_hwtstamp_tx_in_progress(). A driver not supporting
-  hardware time stamping doesn't do that. A driver must never
-  touch sk_buff::tstamp! It is used to store how time stamping
-  for an outgoing packets is to be done.
+  that the driver is doing the time stamping by setting the field
+  skb_tx(skb)->in_progress non-zero. You might want to keep a pointer
+  to the associated skb for the next step and not free the skb. A driver
+  not supporting hardware time stamping doesn't do that. A driver must
+  never touch sk_buff::tstamp! It is used to store software generated
+  time stamps by the network subsystem.
 - As soon as the driver has sent the packet and/or obtained a
   hardware time stamp for it, it passes the time stamp back by
   calling skb_hwtstamp_tx() with the original skb, the raw
-  hardware time stamp and a handle to the device (necessary
-  to convert the hardware time stamp to system time). If obtaining
-  the hardware time stamp somehow fails, then the driver should
-  not fall back to software time stamping. The rationale is that
-  this would occur at a later time in the processing pipeline
-  than other software time stamping and therefore could lead
-  to unexpected deltas between time stamps.
-- If the driver did not call skb_hwtstamp_tx_in_progress(), then
+  hardware time stamp. skb_hwtstamp_tx() clones the original skb and
+  adds the timestamps, therefore the original skb has to be freed now.
+  If obtaining the hardware time stamp somehow fails, then the driver
+  should not fall back to software time stamping. The rationale is that
+  this would occur at a later time in the processing pipeline than other
+  software time stamping and therefore could lead to unexpected deltas
+  between time stamps.
+- If the driver did not call set skb_tx(skb)->in_progress, then
   dev_hard_start_xmit() checks whether software time stamping
   is wanted as fallback and potentially generates the time stamp.

+
+Required properties:
+  - compatible
+      Usage: required
+      Value type: <string>
+      Definition: A standard property.  Specify a string that indicates what
+          kind of firmware it is.  For QE, this should be "fsl,qe-firmware".

+      Definition: A standard property.  This property contains the firmware
+          binary "blob".
+
+Example:
+	qe1@e0080000 {
+		compatible = "fsl,qe";
+		qe_firmware:qe-firmware {
+			compatible = "fsl,qe-firmware";
+			fsl,firmware = [0x70 0xcd 0x00 0x00 0x01 0x46 0x45 ...];

 Interrupt Handling
 ~~~~~~~~~~~~~~~~~~
-In rare but some cases, the interrupt isn't properly handled as
-default.  You would notice this by the DMA transfer error reported by
-ALSA PCM core, for example.  Using MSI might help in such a case.
-Pass `enable_msi=1` option for enabling MSI.
+HD-audio driver uses MSI as default (if available) since 2.6.33
+kernel as MSI works better on some machines, and in general, it's
+better for performance.  However, Nvidia controllers showed bad
+regressions with MSI (especially in a combination with AMD chipset),
+thus we disabled MSI for them.
+
+There seem also still other devices that don't work with MSI.  If you
+see a regression wrt the sound quality (stuttering, etc) or a lock-up
+in the recent kernel, try to pass `enable_msi=0` option to disable
+MSI.  If it works, you can add the known bad device to the blacklist
+defined in hda_intel.c.  In such a case, please report and give the
+patch back to the upstream developer.

-Running Linux on the Voyager Architecture
-=========================================
-
-For full details and current project status, see
-
-http://www.hansenpartnership.com/voyager
-
-The voyager architecture was designed by NCR in the mid 80s to be a
-fully SMP capable RAS computing architecture built around intel's 486
-chip set.  The voyager came in three levels of architectural
-sophistication: 3,4 and 5 --- 1 and 2 never made it out of prototype.
-The linux patches support only the Level 5 voyager architecture (any
-machine class 3435 and above).
-
-The Voyager Architecture
-------------------------
-
-Voyager machines consist of a Baseboard with a 386 diagnostic
-processor, a Power Supply Interface (PSI) a Primary and possibly
-Secondary Microchannel bus and between 2 and 20 voyager slots.  The
-voyager slots can be populated with memory and cpu cards (up to 4GB
-memory and from 1 486 to 32 Pentium Pro processors).  Internally, the
-voyager has a dual arbitrated system bus and a configuration and test
-bus (CAT).  The voyager bus speed is 40MHz.  Therefore (since all
-voyager cards are dual ported for each system bus) the maximum
-transfer rate is 320Mb/s but only if you have your slot configuration
-tuned (only memory cards can communicate with both busses at once, CPU
-cards utilise them one at a time).
-
-Voyager SMP
------------
-
-Since voyager was the first intel based SMP system, it is slightly
-more primitive than the Intel IO-APIC approach to SMP.  Voyager allows
-arbitrary interrupt routing (including processor affinity routing) of
-all 16 PC type interrupts.  However it does this by using a modified
-5259 master/slave chip set instead of an APIC bus.  Additionally,
-voyager supports Cross Processor Interrupts (CPI) equivalent to the
-APIC IPIs.  There are two routed voyager interrupt lines provided to
-each slot.
-
-Processor Cards
----------------
-
-These come in single, dyadic and quad configurations (the quads are
-problematic--see later).  The maximum configuration is 8 quad cards
-for 32 way SMP.
-
-Quad Processors
----------------
-
-Because voyager only supplies two interrupt lines to each Processor
-card, the Quad processors have to be configured (and Bootstrapped) in
-as a pair of Master/Slave processors.
-
-In fact, most Quad cards only accept one VIC interrupt line, so they
-have one interrupt handling processor (called the VIC extended
-processor) and three non-interrupt handling processors.
-
-Current Status
---------------
-
-The System will boot on Mono, Dyad and Quad cards.  There was
-originally a Quad boot problem which has been fixed by proper gdt
-alignment in the initial boot loader.  If you still cannot get your
-voyager system to boot, email me at:
-
-<J.E.J.Bottomley@HansenPartnership.com>
-
-
-The Quad cards now support using the separate Quad CPI vectors instead
-of going through the VIC mailbox system.
-
-The Level 4 architecture (3430 and 3360 Machines) should also work
-fine.
-
-Dump Switch
------------
-
-The voyager dump switch sends out a broadcast NMI which the voyager
-code intercepts and does a task dump.
-
-Power Switch
-------------
-
-The front panel power switch is intercepted by the kernel and should
-cause a system shutdown and power off.
-
-A Note About Mixed CPU Systems
-------------------------------
-
-Linux isn't designed to handle mixed CPU systems very well.  In order
-to get everything going you *must* make sure that your lowest
-capability CPU is used for booting.  Also, mixing CPU classes
-(e.g. 486 and 586) is really not going to work very well at all.

-	  to use devices as you hotplug them.

+ *
+ * This function will parse the "ranges" property of a PCI host bridge device
+ * node and setup the resource mapping of a pci controller based on its
+ * content.
+ *
+ * Life would be boring if it wasn't for a few issues that we have to deal
+ * with here:
+ *
+ *   - We can only cope with one IO space range and up to 3 Memory space
+ *     ranges. However, some machines (thanks Apple !) tend to split their
+ *     space into lots of small contiguous ranges. So we have to coalesce.
+ *
+ *   - We can only cope with all memory ranges having the same offset
+ *     between CPU addresses and PCI addresses. Unfortunately, some bridges
+ *     are setup for a large 1:1 mapping along with a small "window" which
+ *     maps PCI address 0 to some arbitrary high address of the CPU space in
+ *     order to give access to the ISA memory hole.
+ *     The way out of here that I've chosen for now is to always set the
+ *     offset based on the first resource found, then override it if we
+ *     have a different offset and the previous was set by an ISA hole.
+ *
+ *   - Some busses have IO space not starting at 0, which causes trouble with
+ *     the way we do our IO resource renumbering. The code somewhat deals with
+ *     it for 64 bits but I would expect problems on 32 bits.
+ *
+ *   - Some 32 bits platforms such as 4xx can have physical space larger than
+ *     32 bits so we need to use 64 bits values for the parsing

-
-1998-08-26  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (rs_open): Correctly decrement the module in-use count
-		on errors.
-
-Thu Feb 19 14:24:08 1998  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (tty_name): Remove the non-reentrant (and non-SMP safe)
-		version of tty_name, and rename the reentrant _tty_name
-		function to be tty_name.
-		(tty_open): Add a warning message stating callout devices
-		are deprecated.
-
-Mon Dec  1 08:24:15 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (tty_get_baud_rate): Print a warning syslog if the
-		tty->alt_speed kludge is used; this means the system is
-		using the deprecated SPD_HI ioctls.
-
-Mon Nov 24 10:37:49 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c, esp.c, rocket.c: Change drivers to take advantage of
-	 	tty_get_baud_rate().
-	
-	* tty_io.c (tty_get_baud_rate): New function which computes the
-		correct baud rate for the tty.  More factoring out of
-		common code out of the serial driver to the high-level tty
-		functions....
-
-Sat Nov 22 07:53:36 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c, esp.c, rocket.c: Add tty->driver.break() routine, and
- 		allow high-level tty code to handle the break and soft
- 		carrier ioctls.
-	
-	* tty_ioctl.c (n_tty_ioctl): Support TIOCGSOFTCAR and
- 		TIOCSSOFTCAR, so that device drivers don't have to support
- 		it.
-
-	* serial.c (autoconfig): Change 16750 test to hopefully eliminate
-		false results by people with strange 16550As being
-		detected as 16750s.  Hopefully 16750s will still be
-		detected as 16750, and other weird UARTs won't get poorly
-		autodetected.  If this doesn't work, I'll have to disable
-		the auto identification for the 16750.
-
-	* tty_io.c (tty_hangup): Now actually do the tty hangup
-		processing during the timer processing, and disable
-		interrupts while doing the hangup processing.  This avoids
-		several nasty race conditions which happened when the
-		hangup processing was done asynchronously.
-		(tty_ioctl): Do break handling in the tty driver if
-		driver's break function is supported.  
-		(tty_flip_buffer_push): New exported function which should
-		be used by drivers to push characters in the flip buffer
-		to the tty handler.  This may either be done using a task
-		queue function for better CPU efficiency, or directly for
-		low latency operation.
-
-	* serial.c (rs_set_termios): Fix bug rs_set_termios when
-		transitioning away from B0, submitted by Stanislav
-		Voronyi. 
-
-Thu Jun 19 20:05:58 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (begin_break, end_break, rs_ioctl): Applied patch
-		to support BSD ioctls to set and clear the break
-		condition explicitly.
-
-	* console.c (scrup, scrdown, insert_line, delete_line): Applied
-		fix suggested by Aaron Tiensivu to speed up block scrolls
-		up and down.
-
-	* n_tty.c (opost_block, write_chan): Added a modified "fast
- 		console" patch which processes a block of text via
-		"cooking" efficiently.
-
-Wed Jun 18 15:25:50 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (init_dev, release_dev): Applied fix suggested by Bill
-		Hawes to prevent race conditions in the tty code.
-
-	* n_tty.c (n_tty_chars_in_buffer): Applied fix suggested by Bill
-		Hawes so that n_tty_chars_in_buffer returns the correct
-		value in the case when the tty is in cannonical mode.  (To
-		avoid a pty deadlock with telnetd.)
-
-Thu Feb 27 01:53:08 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (change_speed): Add support for the termios flag
-		CMSPAR, which allows the user to select stick parity.
-		(i.e, if PARODD is set, the parity bit is always 1; if
-		PARRODD is not set, then the parity bit is always 0).
-
-Wed Feb 26 19:03:10 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (cleanup_module): Fix memory leak when using the serial
-		driver as a module; make sure tmp_buf gets freed!
-
-Tue Feb 25 11:01:59 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (set_modem_info): Add support for setting and clearing
-		the OUT1 and OUT2 bits.  (For special case UART's, usually
-		for half-duplex.)
-		(autoconfig, change_speed): Fix TI 16750 support.
-
-Sun Feb 16 00:14:43 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (release_dev): Add sanity check to make sure there are
-		no waiters on tty->read_wait or tty->write_wait.
-
-	* serial.c (rs_init): Don't autoconfig a device if the I/O region
-		is already reserved.
-
-	* serial.c (serial_proc_info): Add support for /proc/serial.
-
-Thu Feb 13 00:49:10 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (receive_chars): When the UART repotrs an overrun
- 		condition, it does so with a valid character.  Changed to
- 		not throw away the valid character, but instead report the
-		overrun after the valid character.
-
-	* serial.c: Added new #ifdef's for some of the advanced serial
-		driver features.  A minimal driver that only supports COM
-		1/2/3/4 without sharing serial interrupts only takes 17k;
-		the full driver takes 32k.
-		
-Wed Feb 12 14:50:44 1997  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* vt.c:
-	* pty.c: 
-	* tty_ioctl.c: 
-	* serial.c: Update routines to use the new 2.1 memory access
-	 	routines.
-
-Wed Dec  4 07:51:52 1996  Theodore Ts'o  <tytso@localhost.mit.edu>
-
-	* serial.c (change_speed): Use save_flags(); cli() and
-		restore_flags() in order to ensure we don't accidentally
-		turn on interrupts when starting up the port.
-		(startup): Move the insertion of serial structure into the
-		IRQ chain earlier into the startup processing.  Interrupts
-		should be off this whole time, but we eventually will want
-		to reduce this window.
-
-Thu Nov 21 10:05:22 1996  Theodore Ts'o  <tytso@localhost.mit.edu>
-
-	* tty_ioctl.c (tty_wait_until_sent): Always check the driver
- 		wait_until_ready routine, even if there are no characters
- 		in the xmit buffer.  (There may be charactes in the device
- 		FIFO.)
-		(n_tty_ioctl): Add new flag tty->flow_stopped which
- 		indicates whether the tty is stopped due to a request by
- 		the TCXONC ioctl (used by tcflow).  If so, don't let an
- 		incoming XOFF character restart the tty.  The tty can only
- 		be restarted by another TCXONC request.
-
-	* tty_io.c (start_tty): Don't allow the tty to be restarted if
-		tty->flow_stopped is true.
-
-	* n_tty.c (n_tty_receive_char): If tty->flow_stopped is true, and
- 		IXANY is set, don't eat a character trying to restart the
- 		tty.
-
-	* serial.c (startup): Remove need for MCR_noint from the
- 		async_struct structure.  Only turn on DTR and RTS if the
- 		baud rate is not zero.
-		(change_speed): More accurately calculate the timeout
- 		value based on the word size.  Move responsibility of
- 		hangup when speed becomes B0 to rs_set_termios()
-		(set_serial_info): When changing the UART type set the
- 		current xmit_fifo_size as well as the permanent
- 		xmit_fifo_size.
-		(rs_ioctl): Fix TCSBRK (used by tcdrain) and TCSBRKP
- 		ioctls to return EINTR if interrupted by a signal.
-		(rs_set_termios): If the baud rate changes to or from B0,
- 		this function is now responsible for setting or clearing
- 		DTR and RTS.  DTR and RTS are only be changed on the
- 		transition to or from the B0 state.
-		(rs_close): Wait for the characters to drain based on
- 		info->timeout.  At low baud rates (50 bps), it may take a
- 		long time for the FIFO to completely drain out!
-		(rs_wait_until_sent): Fixed timeout handling.  Now
- 		releases control to the scheduler, but checks frequently
- 		enough so that the function is sensitive enough to pass
- 		the timing requirements of the NIST-PCTS.
-		(block_til_ready): When opening the device, don't turn on
- 		DTR and RTS if the baud rate is B0.
-
-Thu Nov 14 00:06:09 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c (autoconfig): Fix autoconfiguration problems;
-		info->flags wasn't getting initialized from the state
-		structure.  Put in more paranoid test for the 16750.
-
-Fri Nov  8 20:19:50 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* n_tty.c (n_tty_flush_buffer): Only call driver->unthrottle() if
- 		the tty was previous throttled.
-		(n_tty_set_termios, write_chan): Add changes suggested by
- 			Simon P. Allen to allow hardware cooking.
-
-	* tty_ioctl.c (set_termios): If we get a signal while waiting for
-		the tty to drain, return -EINTR.
-	
-	* serial.c (change_speed): Add support for CREAD, as required by
-	 	POSIX.
-
-Sat Nov  2 20:43:10 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* serial.c: Wholesale changes.  Added support for the Startech
- 		16650 and 16650V2 chips.  (WARNING: the new startech
- 		16650A may or may not work!)  Added support for the
- 		TI16750 (not yet tested).  Split async_struct into a
- 		transient part (async_struct) and a permanent part
-		(serial_state) which contains the configuration
- 		information for the ports.  Added new driver routines
- 		wait_until_sent() and send_xchar() to help with POSIX
- 		compliance.  Added support for radio clocks which waggle
-		the carrier detect line (CONFIG_HARD_PPS).
-	
-	* tty_ioctl.c (tty_wait_until_sent): Added call to new driver
-		function tty->driver.wait_until_sent(), which returns when
-		the tty's device xmit buffers are drained.  Needed for
-		full POSIX compliance.
-
-		(send_prio_char): New function, called by the ioctl's
-		TCIOFF and TCION; uses the new driver call send_xchar(),
-		which will send the XON or XOFF character at high priority
-		(and even if tty output is stopped).
-
-Wed Jun  5 18:52:04 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* pty.c (pty_close): When closing a pty, make sure packet mode is
-	 	cleared.
-
-Sun May 26 09:33:52 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* vesa_blank.c (set_vesa_blanking): Add missing verify_area() call.
-
-	* selection.c (set_selection): Add missing verify_area() call.
-
-	* tty_io.c (tty_ioctl): Add missing verify_area() calls.
-
-	* serial.c (rs_ioctl): Add missing verify_area() calls.
-		(rs_init): Allow initialization of serial driver
-		configuration from a module.
-
-	* random.c (extract_entropy): Add missing verify_area call.
-		Don't limit number of characters returned to
-		32,768. Extract entropy is now no longer a inlined
-		function.
-
-		(random_read): Check return value in case extract_entropy
-		returns an error.
-
-		(secure_tcp_sequence_number): New function which returns a
-		secure TCP sequence number.  This is needed to prevent some
-		nasty TCP hijacking attacks.
-	
-		(init_std_data): Initialize using gettimeofday() instead of
-		struct timeval xtime.
-
-		(fast_add_entropy_word, add_entropy_word): Rename the
-		inline function add_entropy_word() to
-		fast_add_entropy_word().  Make add_entropy_word() be the
-		non-inlined function which is used in non-timing critical
-		places, in order to save space.
-
-		(initialize_benchmark, begin_benchmark, end_benchmark): New
-		functions defined when RANDOM_BENCHMARK is defined.  They
-		allow us to benchmark the speed of the
-		add_timer_randomness() call.
-
-		(int_ln, rotate_left): Add two new inline functions with
-		i386 optimized asm instructions.  This speeds up the
-		critical add_entropy_word() and add_timer_randomness()
-		functions, which are called from interrupt handlers.
-
-Tue May  7 22:51:11 1996    <tytso@rsts-11.mit.edu>
-
-	* random.c (add_timer_randomness): Limit the amount randomness
-		that we estimate to 12 bits.  (An arbitrary amount).
-
-		(extract_entropy): To make it harder to analyze the hash
-		function, fold the hash function in half using XOR, and
-		use the folded result as the value to emit to the user.
-		Also, add timer randomness each pass through the
-		exact_entropy call, to increase the amount of unknown
-		values during the extraction process.
-
-		(random_ioctl): Use IOR/IOW definitions to define the
-		ioctl values used by the /dev/random driver.  Allow the
-		old ioctl values to be used for backwards compatibility
-		(for a limited amount of time).
-
-Wed Apr 24 14:02:04 1996  Theodore Ts'o  <tytso@rsts-11.mit.edu>
-
-	* random.c (add_timer_randomness): Use 2nd derivative as well to
-		better estimate entropy.
-
-		(rand_initialize): Explicitly initialize all the pointers
-		to NULL.  (Clearing pointers using memset isn't portable.)
-		Initialize the random pool with OS-dependent data.
-
-		(random_write): Add sanity checking to the arguments to
-		random_write(), so that bad arguments won't cause a kernel
-		SEGV. 
-
-		(random_read): Update the access time of the device inode
-		when you return data to the user.
-
-		(random_ioctl): Wake up the random_wait channel when there
-		are only WAIT_INPUT_BITS available.  Add more paranoia
-		checks to make sure entropy_count doesn't go beyond the
-		bounds of (0, POOLSIZE).  Add a few missing verify_area
-		checks.  Add support for the RNDCLEARPOOL ioctl, which
-		zaps the random pool.
-
-		(add_timer_randomness): Wake up the random_wait
-		channel only when there are WAIT_INPUT_BITS available.
-
-		(random_select): Allow a random refresh daemon process to
-		select on /dev/random for writing; wake up the daemon when
-		there are less than WAIT_OUTPUT_BITS bits of randomness
-		available.
-
-Tue Apr 23 22:56:07 1996    <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (init_dev): Change return code when user attempts to
-		open master pty which is already open from EAGAIN to EIO,
-		to match with BSD expectations.  EIO is more correct
-		anyway, since EAGAIN implies that retrying will be
-		successful --- which it might be.... Eventually!!
-
-	* pty.c (pty_open, pty_close): Fix wait loop so that we don't
-		busy loop while waiting for the master side to open.
-		Fix tty opening/closing logic.  TTY_SLAVE_CLOSED was
-		renamed to TTY_OTHER_CLOSED, so that the name is more
-		descriptive.  Also fixed code so that the tty flag
-		actually works correctly now....
-
-Mon Apr  1 10:22:01 1996    <tytso@rsts-11.mit.edu>
-
-	* serial.c (rs_close): Cleaned up modularization changes.
-		Remove code which forced line discipline back to N_TTY
-		this is done in the tty upper layers, and there's no
-		reason to do it here.  (Making this change also
-		removed the requirement that the serial module access
-		the internal kernel symbol "ldiscs".)
-
-	* tty_io.c (tty_init): Formally register a tty_driver entry for
-		/dev/tty (device 4, 0) and /dev/console (device 5, 0).
-		This guarantees that major device numbers 4 and 5 will be
-		reserved for the tty subsystem (as they have to be because
-		of /dev/tty and /dev/console).  Removed tty_regdev, as
-		this interface is no longer necessary.
-
-Sun Mar 17 20:42:47 GMT 1996 <ah@doc.ic.ac.uk>
-
-	* serial.c : modularisation (changes in linux/fs/device.c allow
-		kerneld to automatically load the serial module).
-
-	* Makefile, Config.in : serial modularisation adds.
-
-	* tty_io.c : tty_init_ctty used by to register "cua" driver just
-		for the /dev/tty device (5,0).  Added tty_regdev.
-	
-	* serial.c (shutdown, rs_ioctl) : when port shuts down wakeup processes
-	  waiting on delta_msr_wait. The TIOCMIWAIT ioctl returns EIO
-	  if no change was done since the time of call.
-
-Sat Mar 16 14:33:13 1996 <aeb@cwi.nl>
-
-	* tty_io.c (disassociate_ctty): If disassociate_ctty is called by
-		exit, do not perform an implicit vhangup on a pty.
-
-Fri Feb  9 14:15:47 1996    <tytso@rsts-11.mit.edu>
-
-	* serial.c (block_til_ready): Fixed another race condition which
-		happens if a hangup happens during the open.
-
-Wed Jan 10 10:08:00 1996    <tytso@rsts-11.mit.edu>
-
-	* serial.c (block_til_ready): Remove race condition which happened
-		if a hangup condition happened during the setup of the
-		UART, before rs_open() called block_til_ready().  This
-		caused the info->count counter to be erroneously
-		decremented.
-
-	* serial.c (startup, rs_open): Remove race condition that could
-		cause a memory leak of one page.  (Fortunately, both race
-		conditions were relatively rare in practice.)
-
-Tue Dec  5 13:21:27 1995    <tytso@rsts-11.mit.edu>
-
-	* serial.c (check_modem_status, rs_ioctl): Support the new
-		ioctl()'s TIOCGICOUNT, TIOCMIWAIT.  These allow an
-		application program to wait on a modem serial register
-		status bit change, and to find out how many changes have
-		taken place for the MSR bits.
-
-		(rs_write): Eliminate a race condition which is introduced
-		if it is necessary to wait for the semaphore.
-
-Sat Nov  4 17:14:45 1995    <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (tty_init): Move registration of TTY_MAJOR and
-		TTY_AUX_MAJOR to the end, so that /proc/devices looks
-		prettier. 
-
-	* pty.c (pty_init): Use new major numbers for PTY master and slave
-		devices.  This allow us to have more than 64 pty's.  We
-		register the old pty devices for backwards compatibility.
-		Note that a system should either be using the old pty
-		devices or the new pty devices --- in general, it should
-		try to use both, since they map into the same pty table.
-		The old pty devices are strictly for backwards compatibility.
-
-Wed Oct 11 12:45:24 1995    <tytso@rsts-11.mit.edu>
-
-	* tty_io.c (disassociate_ctty): If disassociate_ctty is called by
-		exit, perform an implicit vhangup on the tty.
-
-	* pty.c (pty_close): When the master pty is closed, send a hangup
-		to the slave pty.
-		(pty_open): Use the flag TTY_SLAVE_CLOSED to test to see
-		if there are any open slave ptys, instead of using
-		tty->link->count.  The old method got confused if there
-		were processes that had hung-up file descriptors on the
-		slave tty.
-
-Tue May  2 00:53:25 1995    <tytso@rsx-11.mit.edu>
-
-	* tty_io.c (tty_set_ldisc): Wait until the output buffer is
-		drained before closing the old line discipline --- needed
-		in only one case: XON/XOFF processing.
-
-	* n_tty.c (n_tty_close): Don't bother waiting until the output
-		driver is closed; in general, the line discipline
-		shouldn't care if the hardware is finished
-		transmitting before the line discipline terminates.
-
-	* tty_io.c (release_dev): Shutdown the line discipline after
-		decrementing the tty count variable; but set the
-		TTY_CLOSING flag so that we know that this tty structure
-		isn't long for this world.
-
-	* tty_io.c (init_dev): Add sanity code to check to see if
-		TTY_CLOSING is set on a tty structure; if so, something
-		bad has happened (probably a line discipline close blocked
-		when it shouldn't have; so do a kernel printk and then
-		return an error).
-
-Wed Apr 26 10:23:44 1995  Theodore Y. Ts'o  <tytso@localhost>
-
-	* tty_io.c (release_dev): Try to shutdown the line discipline
-		*before* decrementing the tty count variable; this removes
-		a potential race condition which occurs when the line
-		discipline close blocks, and another process then tries
-		open the same serial port.
-
-	* serial.c (rs_hangup): When hanging up, flush the output buffer
-		before shutting down the UART.  Otherwise the line
-		discipline close blocks waiting for the characters to get
-		flushed, which never happens until the serial port gets reused.
-
-Wed Apr 12 08:06:16 1995  Theodore Y. Ts'o  <tytso@localhost>
-
-	* serial.c (do_serial_hangup, do_softint, check_modem_status,
-		rs_init):  Hangups are now scheduled via a separate tqueue
-		structure in the async_struct structure, tqueue_hangup.
-		This task is pushed on to the tq_schedule queue, so that
-		it is processed synchronously by the scheduler.
-
-Sat Feb 18 12:13:51 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (disassociate_ctty, tty_open, tty_ioctl): Clear
-		current->tty_old_pgrp field when a session leader
-		acquires a controlling tty, and after a session leader
-		has disassociated from a controlling tty.
-
-Fri Feb 17 09:34:09 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_interrupt_single, rs_interrupt, rs_interrupt_multi): 
-		Change the number of passes made from 64 to be 256,
-		configurable with the #define RS_ISR_PASS_LIMIT.
-
-	* serial.c (rs_init, set_serial_info, get_serial_info, rs_close):
-		Remove support for closing_wait2.  Instead, set
-		tty->closing and rely on the line discipline to prevent
-		echo wars.
-
-	* n_tty.c (n_tty_receive_char):  IEXTEN does not need to be
-		enabled in order for IXANY to be active.
-
-		If tty->closing is set, then only process XON and XOFF
-                characters.
-
-Sun Feb 12 23:57:48 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_timer): Change the interrupt poll time from 60
-		seconds to 10 seconds, configurable with the #define
-		RS_STROBE_TIME.
-
-	* serial.c (rs_interrupt_multi, startup, shutdown, rs_ioctl,
-		set_multiport_struct, get_multiport_struct): Add
-		provisions for a new type of interrupt service routine,
-		which better supports multiple serial ports on a single
-		IRQ.  
-
-Sun Feb  5 19:35:11 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_ioctl.c (n_tty_ioctl, set_termios, tty_wait_until_sent): 
-	* serial.c (rs_ioctl, rs_close): 
-	* cyclades.c (cy_ioctl, cy_close): 
-	* n_tty.c (n_tty_close):  Rename wait_until_sent to
-		tty_wait_until_sent, so that it's a better name to export
-		in ksyms.c.
-
-Sat Feb  4 23:36:20 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_close): Added missing check for closing_wait2 being
-		ASYNC_CLOSING_WAIT_NONE.
-
-Thu Jan 26 09:02:49 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_init, set_serial_info, get_serial_info,
-		rs_close): Support close_wait in the serial driver.
-		This is helpful for slow devices (like serial
-		plotters) so that their outputs don't get flushed upon
-		device close.  This has to be configurable because
-		normally we don't want ports to be hung up for long
-		periods of time during a close when they are not
-		connected to a device, or the device is powered off.
-
-		The default is to wait 30 seconds; in the case of a
-		very slow device, the close_wait timeout should be
-		lengthened.  If it is set to 0, the kernel will wait
-		forever for all of the data to be transmitted.
-
-Thu Jan 17 01:17:20 1995  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (startup, change_speed, rs_init): Add support to detect
-		the StarTech 16650 chip.  Treat it as a 16450 for now,
-		because of its FIFO bugs.
-
-Thu Jan  5 21:21:57 1995  <dahinds@users.sourceforge.net>
-
-	* serial.c: (receive_char): Added counter to prevent infinite loop
-		when a PCMCIA serial device is ejected.
-
-Thu Dec 29 17:53:48 1994    <tytso@rsx-11.mit.edu>
-
-	* tty_io.c (check_tty_count): New procedure which checks
-		tty->count to make sure that it matches with the number of
-		open file descriptors which point at the structure.  If
-		the number doesn't match, it prints a warning message.
-
-Wed Dec 28 15:41:51 1994    <tytso@rsx-11.mit.edu>
-
-	* tty_io.c (do_tty_hangup, disassociate_ctty): At hangup time,
-		save the tty's current foreground process group in the
-		session leader's task structure.  When the session leader
-		terminates, send a SIGHUP, SIGCONT to that process group.
-		This is not required by POSIX, but it's not prohibited
-		either, and it appears to be the least intrusive way
-		to fix a problem that dialup servers have with
-		orphaned process groups caused by modem hangups.
-
-Thu Dec  8 14:52:11 1994    <tytso@rsx-11.mit.edu>
-
-	* serial.c (rs_ioctl): Don't allow most ioctl's if the serial port
-		isn't initialized.
-
-	* serial.c (rs_close): Don't clear the IER if the serial port
-		isn't initialized. 
-
-	* serial.c (block_til_ready): Don't try to block on the dialin
-		port if the serial port isn't initialized.
-
-Wed Dec  7 10:48:30 1994  Si Park (si@wimpol.demon.co.uk)
-	* tty_io.c (tty_register_driver): Fix bug when linking onto
-		the tty_drivers list. We now test that there are elements
-		already on the list before setting the back link from the
-		first element to the new driver.
-
-	* tty_io.c (tty_unregister_driver): Fix bug in unlinking the
-		specified driver from the tty_drivers list. We were not
-		setting the back link correctly. This used to result in
-		a dangling back link pointer and cause panics on the next
-		call to get_tty_driver().
-
-Tue Nov 29 10:21:09 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (tty_unregister_driver): Fix bug in
-		tty_unregister_driver where the pointer to the refcount is
-		tested, instead of the refcount itself.  This caused
-		tty_unregister_driver to always return EBUSY.
-
-Sat Nov 26 11:59:24 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (tty_ioctl): Add support for the new ioctl
-		TIOCTTYGSTRUCT, which allow a kernel debugging program
-		direct read access to the tty and tty_driver structures.
-
-Fri Nov 25 17:26:22 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_set_termios): Don't wake up processes blocked in
-		open when the CLOCAL flag changes, since a blocking
-		open only samples the CLOCAL flag once when it blocks,
-		and doesn't check it again.  (n.b.  FreeBSD has a
-		different behavior for blocking opens; it's not clear
-		whether Linux or FreeBSD's interpretation is correct.
-		POSIX doesn't give clear guidance on this issue, so
-		this may change in the future....)
-
-	* serial.c (block_til_ready): Use the correct termios structure to
-		check the CLOCAL flag.  If the cuaXX device is active,
-		then check the saved termios for the ttySXX device.
-		Otherwise, use the currently active termios structure.
-
-Sun Nov  6 21:05:44 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (change_speed): Add support for direct access of
-		57,600 and 115,200 bps.
-
-Wed Nov  2 10:32:36 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* n_tty.c (n_tty_receive_room): Only allow excess characters
-		through if we are in ICANON mode *and* there are other no
-		pending lines in the buffer.  Otherwise cut and paste over
-		4k breaks.
-
-Sat Oct 29 18:17:34 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_ioctl, get_lsr_info): Added patch suggested by Arne
-		Riiber so that user mode programs can tell when the
-		transmitter shift register is empty.
-
-Thu Oct 27 23:14:29 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_ioctl.c (wait_until_sent): Added debugging printk statements
-		(under the #ifdef TTY_DEBUG_WAIT_UNTIL_SENT)  
-
-	* serial.c (rs_interrupt, rs_interrupt_single, receive_chars,
-		change_speed, rs_close): rs_close now disables receiver
-		interrupts when closing the serial port.  This allows the
-		serial port to close quickly when Linux and a modem (or a
-		mouse) are engaged in an echo war; when closing the serial
-		port, we now first stop listening to incoming characters,
-		and *then* wait for the transmit buffer to drain.  
-
-		In order to make this change, the info->read_status_mask
-		is now used to control what bits of the line status
-		register are looked at in the interrupt routine in all
-		cases; previously it was only used in receive_chars to
-		select a few of the status bits.
-
-Mon Oct 24 23:36:21 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_close): Add a timeout to the transmitter flush
-		loop; this is just a sanity check in case we have flaky
-		(or non-existent-but-configured-by-the-user) hardware.
-
-Fri Oct 21 09:37:23 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (tty_fasync): When asynchronous I/O is enabled, if the
-		process or process group has not be specified yet, set it
-		to be the tty's process group, or if that is not yet set,
-		to the current process's pid.
-
-Thu Oct 20 23:17:28 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* n_tty.c (n_tty_receive_room): If we are doing input
-		canonicalization, let as many characters through as
-		possible, so that the excess characters can be "beeped".
-
-Tue Oct 18 10:02:43 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_start): Removed an incorrect '!' that was
-		preventing transmit interrupts from being re-enabled in
-		rs_start().  Fortunately in most cases it would be
-		re-enabled elsewhere, but this still should be fixed
-		correctly.
-
-Sun Oct  9 23:46:03 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (do_tty_hangup): If the tty driver flags
-		TTY_DRIVER_RESET_TERMIOS is set, then reset the termios
-		settings back to the driver's initial configuration.  This
-		allows the termios settings to be reset even if a process
-		has hung up file descriptors keeping a pty's termios from
-		being freed and reset.
-
-	* tty_io.c (release_dev): Fix memory leak.  The pty's other
-		termios structure should also be freed.
-
-	* serial.c (rs_close, shutdown): Change how we wait for the
-		transmitter to completely drain before shutting down the
-		serial port.  We now do it by scheduling in another
-		process instead of busy looping with the interrupts turned
-		on.  This may eliminate some race condition problems that
-		some people seem to be reporting.
-
-Sun Sep 25 14:18:14 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (release_dev): When freeing a tty make sure that both
-		the tty and the o_tty (if present) aren't a process's
-		controlling tty.  (Previously, we only checked the tty.)
-
-	* serial.c (change_speed): Only enable the Modem Status
-		Interrupt for a port if CLOCAL is not set or CRTSCTS
-		is set.  If we're not checking the carrier detect and
-		CTS line, there's no point in enabling the modem
-		status interrupt.  This will save spurious interrupts
-		from slowing down systems who have terminals that
-		don't support either line.  (Of course, if you want
-		only one of CD and CTS support, you will need a
-		properly wired serial cable.)
-
-Thu Sep 22 08:32:48 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (do_SAK): Return if tty is null.
-
-	* tty_io.c (_tty_name): Return "NULL tty" if the passed in tty is
-		NULL.
-
-Sat Sep 17 13:19:25 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_ioctl.c (n_tty_ioctl): Fix TIOCGLCKTRMIOS and
-		TIOCSLCKTRMIOS, which were totally broken.  Remove
-		extra indirection from argument; it should be a struct
-		termios *, not a struct termios **.
-		&real_tty->termios_locked should have been
-		real_tty->termios_locked.  This caused us to be
-		reading and writing the termios_locked structure to
-		random places in kernel memory.  
-
-	* tty_io.c (release_dev): Oops!  Forgot to delete a critical kfree
-		of the locked_termios.  This leaves the locked_termios
-		structure pointed at a freed object.  
-
-Fri Sep 16 08:13:25 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* tty_io.c (tty_open): Don't check for an exclusive open until
-		after the device specific open routine has been called.
-		Otherwise, the serial device ref counting will be screwed
-		up.
-
-	* serial.c (rs_open, block_til_ready): Don't set termios structure
-		until after block_til_ready has returned successfully.
-		Modify block_til_ready to check the normal_termios
-		structure directly, so it doesn't rely on termios being
-		set before it's called.
-
-Thu Sep 15 23:34:01 1994  Theodore Y. Ts'o  (tytso@rt-11)
-
-	* serial.c (rs_close): Turn off interrupts during rs_close() to
-		prevent a race condition with the hangup code (which
-		runs during a software interrupt).
-
-	* tty_io.c (release_dev): Don't free the locked_termios structure;
-		its state must be retained across device opens.
-
-
-	* tty_io.c (tty_unregister_driver): Added function to unregister a
-		tty driver.  (For loadable device drivers.)

+ * Ceph address space ops.
+ *
+ * There are a few funny things going on here.
+ *
+ * The page->private field is used to reference a struct
+ * ceph_snap_context for _every_ dirty page.  This indicates which
+ * snapshot the page was logically dirtied in, and thus which snap
+ * context needs to be associated with the osd write during writeback.
+ *
+ * Similarly, struct ceph_inode_info maintains a set of counters to
+ * count dirty pages on the inode.  In the absense of snapshots,
+ * i_wrbuffer_ref == i_wrbuffer_ref_head == the dirty page count.
+ *
+ * When a snapshot is taken (that is, when the client receives
+ * notification that a snapshot was taken), each inode with caps and
+ * with dirty pages (dirty pages implies there is a cap) gets a new
+ * ceph_cap_snap in the i_cap_snaps list (which is sorted in ascending
+ * order, new snaps go to the tail).  The i_wrbuffer_ref_head count is
+ * moved to capsnap->dirty. (Unless a sync write is currently in
+ * progress.  In that case, the capsnap is said to be "pending", new
+ * writes cannot start, and the capsnap isn't "finalized" until the
+ * write completes (or fails) and a final size/mtime for the inode for
+ * that snap can be settled upon.)  i_wrbuffer_ref_head is reset to 0.
+ *
+ * On writeback, we must submit writes to the osd IN SNAP ORDER.  So,
+ * we look for the first capsnap in i_cap_snaps and write out pages in
+ * that snap context _only_.  Then we move on to the next capsnap,
+ * eventually reaching the "live" or "head" context (i.e., pages that
+ * are not yet snapped) and are writing the most recently dirtied
+ * pages.
+ *
+ * Invalidate and so forth must take care to ensure the dirty page
+ * accounting is preserved.

+ *
+ * If the client holds a *_SHARED cap, the client has a coherent value
+ * that can be safely read from the cached inode.
+ *
+ * In the case of a *_EXCL (exclusive) or FILE_WR capabilities, the
+ * client is allowed to change inode attributes (e.g., file size,
+ * mtime), note its dirty state in the ceph_cap, and asynchronously
+ * flush that metadata change to the MDS.
+ *
+ * In the event of a conflicting operation (perhaps by another
+ * client), the MDS will revoke the conflicting client capabilities.
+ *
+ * In order for a client to cache an inode, it must hold a capability
+ * with at least one MDS server.  When inodes are released, release
+ * notifications are batched and periodically sent en masse to the MDS
+ * cluster to release server state.

+ * Snapshots in ceph are driven in large part by cooperation from the
+ * client.  In contrast to local file systems or file servers that
+ * implement snapshots at a single point in the system, ceph's
+ * distributed access to storage requires clients to help decide
+ * whether a write logically occurs before or after a recently created
+ * snapshot.
+ *
+ * This provides a perfect instantanous client-wide snapshot.  Between
+ * clients, however, snapshots may appear to be applied at slightly
+ * different points in time, depending on delays in delivering the
+ * snapshot notification.
+ *
+ * Snapshots are _not_ file system-wide.  Instead, each snapshot
+ * applies to the subdirectory nested beneath some directory.  This
+ * effectively divides the hierarchy into multiple "realms," where all
+ * of the files contained by each realm share the same set of
+ * snapshots.  An individual realm's snap set contains snapshots
+ * explicitly created on that realm, as well as any snaps in its
+ * parent's snap set _after_ the point at which the parent became it's
+ * parent (due to, say, a rename).  Similarly, snaps from prior parents
+ * during the time intervals during which they were the parent are included.
+ *
+ * The client is spared most of this detail, fortunately... it must only
+ * maintains a hierarchy of realms reflecting the current parent/child
+ * realm relationship, and for each realm has an explicit list of snaps
+ * inherited from prior parents.
+ *
+ * A snap_realm struct is maintained for realms containing every inode
+ * with an open cap in the system.  (The needed snap realm information is
+ * provided by the MDS whenever a cap is issued, i.e., on open.)  A 'seq'
+ * version number is used to ensure that as realm parameters change (new
+ * snapshot, new parent, etc.) the client's realm hierarchy is updated.
+ *
+ * The realm hierarchy drives the generation of a 'snap context' for each
+ * realm, which simply lists the resulting set of snaps for the realm.  This
+ * is attached to any writes sent to OSDs.
+ */

-ToDo/Notes:
-	- Find and fix bugs.
-	- The only places in the kernel where a file is resized are
-	  ntfs_file_write*() and ntfs_truncate() for both of which i_mutex is
-	  held.  Just have to be careful in read-/writepage and other helpers
-	  not running under i_mutex that we play nice.  Also need to be careful
-	  with initialized_size extension in ntfs_file_write*() and writepage.
-	  UPDATE: The only things that need to be checked are the compressed
-	  write and the other attribute resize/write cases like index
-	  attributes, etc.  For now none of these are implemented so are safe.
-	- Implement filling in of holes in aops.c::ntfs_writepage() and its
-	  helpers.
-	- Implement mft.c::sync_mft_mirror_umount().  We currently will just
-	  leave the volume dirty on umount if the final iput(vol->mft_ino)
-	  causes a write of any mirrored mft records due to the mft mirror
-	  inode having been discarded already.  Whether this can actually ever
-	  happen is unclear however so it is worth waiting until someone hits
-	  the problem.
-
-2.1.29 - Fix a deadlock at mount time.
-
-	- During mount the VFS holds s_umount lock on the superblock.  So when
-	  we try to empty the journal $LogFile contents by calling
-	  ntfs_attr_set() when the machine does not have much memory and the
-	  journal is large ntfs_attr_set() results in the VM trying to balance
-	  dirty pages which in turn tries to that the s_umount lock and thus we
-	  get a deadlock.  The solution is to not use ntfs_attr_set() and
-	  instead do the zeroing by hand at the block level rather than page
-	  cache level.
-	- Fix sparse warnings.
-
-2.1.28 - Fix a deadlock.
-
-	- Fix deadlock in fs/ntfs/inode.c::ntfs_put_inode().  Thanks to Sergey
-	  Vlasov for the report and detailed analysis of the deadlock.  The fix
-	  involved getting rid of ntfs_put_inode() altogether and hence NTFS no
-	  longer has a ->put_inode super operation.
-
-2.1.27 - Various bug fixes and cleanups.
-
-	- Fix two compiler warnings on Alpha.  Thanks to Andrew Morton for
-	  reporting them.
-	- Fix an (innocent) off-by-one error in the runlist code.
-	- Fix a buggette in an "should be impossible" case handling where we
-	  continued the attribute lookup loop instead of aborting it.
-	- Use buffer_migrate_page() for the ->migratepage function of all ntfs
-	  address space operations.
-	- Fix comparison of $MFT and $MFTMirr to not bail out when there are
-	  unused, invalid mft records which are the same in both $MFT and
-	  $MFTMirr.
-	- Add support for sparse files which have a compression unit of 0.
-	- Remove all the make_bad_inode() calls.  This should only be called
-	  from read inode and new inode code paths.
-	- Limit name length in fs/ntfs/unistr.c::ntfs_nlstoucs() to maximum
-	  allowed by NTFS, i.e. 255 Unicode characters, not including the
-	  terminating NULL (which is not stored on disk).
-	- Improve comments on file attribute flags in fs/ntfs/layout.h.
-	- Fix a bug in fs/ntfs/inode.c::ntfs_read_locked_index_inode() where we
-	  forgot to update a temporary variable so loading index inodes which
-	  have an index allocation attribute failed.
-	- Add a missing call to flush_dcache_mft_record_page() in
-	  fs/ntfs/inode.c::ntfs_write_inode().
-	- Handle the recently introduced -ENAMETOOLONG return value from
-	  fs/ntfs/unistr.c::ntfs_nlstoucs() in fs/ntfs/namei.c::ntfs_lookup().
-	- Semaphore to mutex conversion.  (Ingo Molnar)
-
-2.1.26 - Minor bug fixes and updates.
-
-	- Fix a potential overflow in file.c where a cast to s64 was missing in
-	  a left shift of a page index.
-	- The struct inode has had its i_sem semaphore changed to a mutex named
-	  i_mutex.
-	- We have struct kmem_cache now so use it instead of the typedef
-	  kmem_cache_t.  (Pekka Enberg)
-	- Implement support for sector sizes above 512 bytes (up to the maximum
-	  supported by NTFS which is 4096 bytes).
-	- Do more detailed reporting of why we cannot mount read-write by
-	  special casing the VOLUME_MODIFIED_BY_CHKDSK flag.
-	- Miscellaneous updates to layout.h.
-	- Cope with attribute list attribute having invalid flags.  Windows
-	  copes with this and even chkdsk does not detect or fix this so we
-	  have to cope with it, too.  Thanks to Pawel Kot for reporting the
-	  problem.
-
-2.1.25 - (Almost) fully implement write(2) and truncate(2).
-
-	- Change ntfs_map_runlist_nolock(), ntfs_attr_find_vcn_nolock() and
-	  {__,}ntfs_cluster_free() to also take an optional attribute search
-	  context as argument.  This allows calling these functions with the
-	  mft record mapped.  Update all callers.
-	- Fix potential deadlock in ntfs_mft_data_extend_allocation_nolock()
-	  error handling by passing in the active search context when calling
-	  ntfs_cluster_free().
-	- Change ntfs_cluster_alloc() to take an extra boolean parameter
-	  specifying whether the cluster are being allocated to extend an
-	  attribute or to fill a hole.
-	- Change ntfs_attr_make_non_resident() to call ntfs_cluster_alloc()
-	  with @is_extension set to TRUE and remove the runlist terminator
-	  fixup code as this is now done by ntfs_cluster_alloc().
-	- Change ntfs_attr_make_non_resident to take the attribute value size
-	  as an extra parameter.  This is needed since we need to know the size
-	  before we can map the mft record and our callers always know it.  The
-	  reason we cannot simply read the size from the vfs inode i_size is
-	  that this is not necessarily uptodate.  This happens when
-	  ntfs_attr_make_non_resident() is called in the ->truncate call path.
-	- Fix ntfs_attr_make_non_resident() to update the vfs inode i_blocks
-	  which is zero for a resident attribute but should no longer be zero
-	  once the attribute is non-resident as it then has real clusters
-	  allocated.
-	- Add fs/ntfs/attrib.[hc]::ntfs_attr_extend_allocation(), a function to
-	  extend the allocation of an attributes.  Optionally, the data size,
-	  but not the initialized size can be extended, too.
-	- Implement fs/ntfs/inode.[hc]::ntfs_truncate().  It only supports
-	  uncompressed and unencrypted files and it never creates sparse files
-	  at least for the moment (making a file sparse requires us to modify
-	  its directory entries and we do not support directory operations at
-	  the moment).  Also, support for highly fragmented files, i.e. ones
-	  whose data attribute is split across multiple extents, is severly
-	  limited.  When such a case is encountered, EOPNOTSUPP is returned.
-	- Enable ATTR_SIZE attribute changes in ntfs_setattr().  This completes
-	  the initial implementation of file truncation.  Now both open(2)ing
-	  a file with the O_TRUNC flag and the {,f}truncate(2) system calls
-	  will resize a file appropriately.  The limitations are that only
-	  uncompressed and unencrypted files are supported.  Also, there is
-	  only very limited support for highly fragmented files (the ones whose
-	  $DATA attribute is split into multiple attribute extents).
-	- In attrib.c::ntfs_attr_set() call balance_dirty_pages_ratelimited()
-	  and cond_resched() in the main loop as we could be dirtying a lot of
-	  pages and this ensures we play nice with the VM and the system as a
-	  whole.
-	- Implement file operations ->write, ->aio_write, ->writev for regular
-	  files.  This replaces the old use of generic_file_write(), et al and
-	  the address space operations ->prepare_write and ->commit_write.
-	  This means that both sparse and non-sparse (unencrypted and
-	  uncompressed) files can now be extended using the normal write(2)
-	  code path.  There are two limitations at present and these are that
-	  we never create sparse files and that we only have limited support
-	  for highly fragmented files, i.e. ones whose data attribute is split
-	  across multiple extents.   When such a case is encountered,
-	  EOPNOTSUPP is returned.
-	- $EA attributes can be both resident and non-resident.
-	- Use %z for size_t to fix compilation warnings.  (Andrew Morton)
-	- Fix compilation warnings with gcc-4.0.2 on SUSE 10.0.
-	- Document extended attribute ($EA) NEED_EA flag.  (Based on libntfs
-	  patch by Yura Pakhuchiy.)
-
-2.1.24 - Lots of bug fixes and support more clean journal states.
-
-	- Support journals ($LogFile) which have been modified by chkdsk.  This
-	  means users can boot into Windows after we marked the volume dirty.
-	  The Windows boot will run chkdsk and then reboot.  The user can then
-	  immediately boot into Linux rather than having to do a full Windows
-	  boot first before rebooting into Linux and we will recognize such a
-	  journal and empty it as it is clean by definition.  Note, this only
-	  works if chkdsk left the journal in an obviously clean state.
-	- Support journals ($LogFile) with only one restart page as well as
-	  journals with two different restart pages.  We sanity check both and
-	  either use the only sane one or the more recent one of the two in the
-	  case that both are valid.
-	- Add fs/ntfs/malloc.h::ntfs_malloc_nofs_nofail() which is analogous to
-	  ntfs_malloc_nofs() but it performs allocations with __GFP_NOFAIL and
-	  hence cannot fail.
-	- Use ntfs_malloc_nofs_nofail() in the two critical regions in
-	  fs/ntfs/runlist.c::ntfs_runlists_merge().  This means we no longer
-	  need to panic() if the allocation fails as it now cannot fail.
-	- Fix two nasty runlist merging bugs that had gone unnoticed so far.
-	  Thanks to Stefano Picerno for the bug report.
-	- Remove two bogus BUG_ON()s from fs/ntfs/mft.c.
-	- Fix handling of valid but empty mapping pairs array in
-	  fs/ntfs/runlist.c::ntfs_mapping_pairs_decompress().
-	- Report unrepresentable inodes during ntfs_readdir() as KERN_WARNING
-	  messages and include the inode number.  Thanks to Yura Pakhuchiy for
-	  pointing this out.
-	- Change ntfs_rl_truncate_nolock() to throw away the runlist if the new
-	  length is zero.
-	- Add runlist.[hc]::ntfs_rl_punch_nolock() which punches a caller
-	  specified hole into a runlist.
-	- Fix a bug in fs/ntfs/index.c::ntfs_index_lookup().  When the returned
-	  index entry is in the index root, we forgot to set the @ir pointer in
-	  the index context.  Thanks to Yura Pakhuchiy for finding this bug.
-	- Remove bogus setting of PageError in ntfs_read_compressed_block().
-	- Add fs/ntfs/attrib.[hc]::ntfs_resident_attr_value_resize().
-	- Fix a bug in ntfs_map_runlist_nolock() where we forgot to protect
-	  access to the allocated size in the ntfs inode with the size lock.
-	- Fix ntfs_attr_vcn_to_lcn_nolock() and ntfs_attr_find_vcn_nolock() to
-	  return LCN_ENOENT when there is no runlist and the allocated size is
-	  zero.
-	- Fix load_attribute_list() to handle the case of a NULL runlist.
-	- Fix handling of sparse attributes in ntfs_attr_make_non_resident().
-	- Add BUG() checks to ntfs_attr_make_non_resident() and ntfs_attr_set()
-	  to ensure that these functions are never called for compressed or
-	  encrypted attributes.
-	- Fix cluster (de)allocators to work when the runlist is NULL and more
-	  importantly to take a locked runlist rather than them locking it
-	  which leads to lock reversal.
-	- Truncate {a,c,m}time to the ntfs supported time granularity when
-	  updating the times in the inode in ntfs_setattr().
-	- Fixup handling of sparse, compressed, and encrypted attributes in
-	  fs/ntfs/inode.c::ntfs_read_locked_{,attr_,index_}inode(),
-	  fs/ntfs/aops.c::ntfs_{read,write}page().
-	- Make ntfs_write_block() not instantiate sparse blocks if they contain
-	  only zeroes.
-	- Optimize fs/ntfs/aops.c::ntfs_write_block() by extending the page
-	  lock protection over the buffer submission for i/o which allows the
-	  removal of the get_bh()/put_bh() pairs for each buffer.
-	- Fix fs/ntfs/aops.c::ntfs_{read,write}_block() to handle the case
-	  where a concurrent truncate has truncated the runlist under our feet.
-	- Fix page_has_buffers()/page_buffers() handling in fs/ntfs/aops.c.
-	- In fs/ntfs/aops.c::ntfs_end_buffer_async_read(), use a bit spin lock
-	  in the first buffer head instead of a driver global spin lock to
-	  improve scalability.
-	- Minor fix to error handling and error message display in
-	  fs/ntfs/aops.c::ntfs_prepare_nonresident_write().
-	- Change the mount options {u,f,d}mask to always parse the number as
-	  an octal number to conform to how chmod(1) works, too.  Thanks to
-	  Giuseppe Bilotta and Horst von Brand for pointing out the errors of
-	  my ways.
-	- Fix various bugs in the runlist merging code.  (Based on libntfs
-	  changes by Richard Russon.)
-	- Fix sparse warnings that have crept in over time.
-	- Change ntfs_cluster_free() to require a write locked runlist on entry
-	  since we otherwise get into a lock reversal deadlock if a read locked
-	  runlist is passed in. In the process also change it to take an ntfs
-	  inode instead of a vfs inode as parameter.
-	- Fix the definition of the CHKD ntfs record magic.  It had an off by
-	  two error causing it to be CHKB instead of CHKD.
-	- Fix a stupid bug in __ntfs_bitmap_set_bits_in_run() which caused the
-	  count to become negative and hence we had a wild memset() scribbling
-	  all over the system's ram.
-
-2.1.23 - Implement extension of resident files and make writing safe as well as
-	 many bug fixes, cleanups, and enhancements...
-
-	- Add printk rate limiting for ntfs_warning() and ntfs_error() when
-	  compiled without debug.  This avoids a possible denial of service
-	  attack.  Thanks to Carl-Daniel Hailfinger from SuSE for pointing this
-	  out.
-	- Fix compilation warnings on ia64.  (Randy Dunlap)
-	- Use i_size_{read,write}() instead of reading i_size by hand and cache
-	  the value where apropriate.
-	- Add size_lock to the ntfs_inode structure.  This is an rw spinlock
-	  and it locks against access to the inode sizes.  Note, ->size_lock
-	  is also accessed from irq context so you must use the _irqsave and
-	  _irqrestore lock and unlock functions, respectively.  Protect all
-	  accesses to allocated_size, initialized_size, and compressed_size.
-	- Minor optimization to fs/ntfs/super.c::ntfs_statfs() and its helpers.
-	- Implement extension of resident files in the regular file write code
-	  paths (fs/ntfs/aops.c::ntfs_{prepare,commit}_write()).  At present
-	  this only works until the data attribute becomes too big for the mft
-	  record after which we abort the write returning -EOPNOTSUPP from
-	  ntfs_prepare_write().
-	- Add disable_sparse mount option together with a per volume sparse
-	  enable bit which is set appropriately and a per inode sparse disable
-	  bit which is preset on some system file inodes as appropriate.
-	- Enforce that sparse support is disabled on NTFS volumes pre 3.0.
-	- Fix a bug in fs/ntfs/runlist.c::ntfs_mapping_pairs_decompress() in
-	  the creation of the unmapped runlist element for the base attribute
-	  extent.
-	- Split ntfs_map_runlist() into ntfs_map_runlist() and a non-locking
-	  helper ntfs_map_runlist_nolock() which is used by ntfs_map_runlist().
-	  This allows us to map runlist fragments with the runlist lock already
-	  held without having to drop and reacquire it around the call.  Adapt
-	  all callers.
-	- Change ntfs_find_vcn() to ntfs_find_vcn_nolock() which takes a locked
-	  runlist.  This allows us to find runlist elements with the runlist
-	  lock already held without having to drop and reacquire it around the
-	  call.  Adapt all callers.
-	- Change time to u64 in time.h::ntfs2utc() as it otherwise generates a
-	  warning in the do_div() call on sparc32.  Thanks to Meelis Roos for
-	  the report and analysis of the warning.
-	- Fix a nasty runlist merge bug when merging two holes.
-	- Set the ntfs_inode->allocated_size to the real allocated size in the
-	  mft record for resident attributes (fs/ntfs/inode.c).
-	- Small readability cleanup to use "a" instead of "ctx->attr"
-	  everywhere (fs/ntfs/inode.c).
-	- Make fs/ntfs/namei.c::ntfs_get_{parent,dentry} static and move the
-	  definition of ntfs_export_ops from fs/ntfs/super.c to namei.c.  Also,
-	  declare ntfs_export_ops in fs/ntfs/ntfs.h.
-	- Correct sparse file handling.  The compressed values need to be
-	  checked and set in the ntfs inode as done for compressed files and
-	  the compressed size needs to be used for vfs inode->i_blocks instead
-	  of the allocated size, again, as done for compressed files.
-	- Add AT_EA in addition to AT_DATA to whitelist for being allowed to be
-	  non-resident in fs/ntfs/attrib.c::ntfs_attr_can_be_non_resident().
-	- Add fs/ntfs/attrib.c::ntfs_attr_vcn_to_lcn_nolock() used by the new
-	  write code.
-	- Fix bug in fs/ntfs/attrib.c::ntfs_find_vcn_nolock() where after
-	  dropping the read lock and taking the write lock we were not checking
-	  whether someone else did not already do the work we wanted to do.
-	- Rename fs/ntfs/attrib.c::ntfs_find_vcn_nolock() to
-	  ntfs_attr_find_vcn_nolock() and update all callers.
-	- Add fs/ntfs/attrib.[hc]::ntfs_attr_make_non_resident().
-	- Fix sign of various error return values to be negative in
-	  fs/ntfs/lcnalloc.c.
-	- Modify ->readpage and ->writepage (fs/ntfs/aops.c) so they detect and
-	  handle the case where an attribute is converted from resident to
-	  non-resident by a concurrent file write.
-	- Remove checks for NULL before calling kfree() since kfree() does the
-	  checking itself.  (Jesper Juhl)
-	- Some utilities modify the boot sector but do not update the checksum.
-	  Thus, relax the checking in fs/ntfs/super.c::is_boot_sector_ntfs() to
-	  only emit a warning when the checksum is incorrect rather than
-	  refusing the mount.  Thanks to Bernd Casimir for pointing this
-	  problem out.
-	- Update attribute definition handling.
-	- Add NTFS_MAX_CLUSTER_SIZE and NTFS_MAX_PAGES_PER_CLUSTER constants.
-	- Use NTFS_MAX_CLUSTER_SIZE in super.c instead of hard coding 0x10000.
-	- Use MAX_BUF_PER_PAGE instead of variable sized array allocation for
-	  better code generation and one less sparse warning in fs/ntfs/aops.c.
-	- Remove spurious void pointer casts from fs/ntfs/.  (Pekka Enberg)
-	- Use C99 style structure initialization after memory allocation where
-	  possible (fs/ntfs/{attrib.c,index.c,super.c}).  Thanks to Al Viro and
-	  Pekka Enberg.
-	- Stamp the transaction log ($UsnJrnl), aka user space journal, if it
-	  is active on the volume and we are mounting read-write or remounting
-	  from read-only to read-write.
-	- Fix a bug in address space operations error recovery code paths where
-	  if the runlist was not mapped at all and a mapping error occured we
-	  would leave the runlist locked on exit to the function so that the
-	  next access to the same file would try to take the lock and deadlock.
-	- Detect the case when Windows has been suspended to disk on the volume
-	  to be mounted and if this is the case do not allow (re)mounting
-	  read-write.  This is done by parsing hiberfil.sys if present.
-	- Fix several occurences of a bug where we would perform 'var & ~const'
-	  with a 64-bit variable and a int, i.e. 32-bit, constant.  This causes
-	  the higher order 32-bits of the 64-bit variable to be zeroed.  To fix
-	  this cast the 'const' to the same 64-bit type as 'var'.
-	- Change the runlist terminator of the newly allocated cluster(s) to
-	  LCN_ENOENT in ntfs_attr_make_non_resident().  Otherwise the runlist
-	  code gets confused.
-	- Add an extra parameter @last_vcn to ntfs_get_size_for_mapping_pairs()
-	  and ntfs_mapping_pairs_build() to allow the runlist encoding to be
-	  partial which is desirable when filling holes in sparse attributes.
-	  Update all callers.
-	- Change ntfs_map_runlist_nolock() to only decompress the mapping pairs
-	  if the requested vcn is inside it.  Otherwise we get into problems
-	  when we try to map an out of bounds vcn because we then try to map
-	  the already mapped runlist fragment which causes
-	  ntfs_mapping_pairs_decompress() to fail and return error.  Update
-	  ntfs_attr_find_vcn_nolock() accordingly.
-	- Fix a nasty deadlock that appeared in recent kernels.
-	  The situation: VFS inode X on a mounted ntfs volume is dirty.  For
-	  same inode X, the ntfs_inode is dirty and thus corresponding on-disk
-	  inode, i.e. mft record, which is in a dirty PAGE_CACHE_PAGE belonging
-	  to the table of inodes, i.e. $MFT, inode 0.
-	  What happens:
-	  Process 1: sys_sync()/umount()/whatever...  calls
-	  __sync_single_inode() for $MFT -> do_writepages() -> write_page for
-	  the dirty page containing the on-disk inode X, the page is now locked
-	  -> ntfs_write_mst_block() which clears PageUptodate() on the page to
-	  prevent anyone else getting hold of it whilst it does the write out.
-	  This is necessary as the on-disk inode needs "fixups" applied before
-	  the write to disk which are removed again after the write and
-	  PageUptodate is then set again.  It then analyses the page looking
-	  for dirty on-disk inodes and when it finds one it calls
-	  ntfs_may_write_mft_record() to see if it is safe to write this
-	  on-disk inode.  This then calls ilookup5() to check if the
-	  corresponding VFS inode is in icache().  This in turn calls ifind()
-	  which waits on the inode lock via wait_on_inode whilst holding the
-	  global inode_lock.
-	  Process 2: pdflush results in a call to __sync_single_inode for the
-	  same VFS inode X on the ntfs volume.  This locks the inode (I_LOCK)
-	  then calls write-inode -> ntfs_write_inode -> map_mft_record() ->
-	  read_cache_page() for the page (in page cache of table of inodes
-	  $MFT, inode 0) containing the on-disk inode.  This page has
-	  PageUptodate() clear because of Process 1 (see above) so
-	  read_cache_page() blocks when it tries to take the page lock for the
-	  page so it can call ntfs_read_page().
-	  Thus Process 1 is holding the page lock on the page containing the
-	  on-disk inode X and it is waiting on the inode X to be unlocked in
-	  ifind() so it can write the page out and then unlock the page.
-	  And Process 2 is holding the inode lock on inode X and is waiting for
-	  the page to be unlocked so it can call ntfs_readpage() or discover
-	  that Process 1 set PageUptodate() again and use the page.
-	  Thus we have a deadlock due to ifind() waiting on the inode lock.
-	  The solution: The fix is to use the newly introduced
-	  ilookup5_nowait() which does not wait on the inode's lock and hence
-	  avoids the deadlock.  This is safe as we do not care about the VFS
-	  inode and only use the fact that it is in the VFS inode cache and the
-	  fact that the vfs and ntfs inodes are one struct in memory to find
-	  the ntfs inode in memory if present.  Also, the ntfs inode has its
-	  own locking so it does not matter if the vfs inode is locked.
-	- Fix bug in mft record writing where we forgot to set the device in
-	  the buffers when mapping them after the VM had discarded them.
-	  Thanks to Martin MOKREJÅ for the bug report.
-
-2.1.22 - Many bug and race fixes and error handling improvements.
-
-	- Improve error handling in fs/ntfs/inode.c::ntfs_truncate().
-	- Change fs/ntfs/inode.c::ntfs_truncate() to return an error code
-	  instead of void and provide a helper ntfs_truncate_vfs() for the
-	  vfs ->truncate method.
-	- Add a new ntfs inode flag NInoTruncateFailed() and modify
-	  fs/ntfs/inode.c::ntfs_truncate() to set and clear it appropriately.
-	- Fix min_size and max_size definitions in ATTR_DEF structure in
-	  fs/ntfs/layout.h to be signed.
-	- Add attribute definition handling helpers to fs/ntfs/attrib.[hc]:
-	  ntfs_attr_size_bounds_check(), ntfs_attr_can_be_non_resident(), and
-	  ntfs_attr_can_be_resident(), which in turn use the new private helper
-	  ntfs_attr_find_in_attrdef().
-	- In fs/ntfs/aops.c::mark_ntfs_record_dirty(), take the
-	  mapping->private_lock around the dirtying of the buffer heads
-	  analagous to the way it is done in __set_page_dirty_buffers().
-	- Ensure the mft record size does not exceed the PAGE_CACHE_SIZE at
-	  mount time as this cannot work with the current implementation.
-	- Check for location of attribute name and improve error handling in
-	  general in fs/ntfs/inode.c::ntfs_read_locked_inode() and friends.
-	- In fs/ntfs/aops.c::ntfs_writepage(), if the page is fully outside
-	  i_size, i.e. race with truncate, invalidate the buffers on the page
-	  so that they become freeable and hence the page does not leak.
-	- Remove unused function fs/ntfs/runlist.c::ntfs_rl_merge().  (Adrian
-	  Bunk)
-	- Fix stupid bug in fs/ntfs/attrib.c::ntfs_attr_find() that resulted in
-	  a NULL pointer dereference in the error code path when a corrupt
-	  attribute was found.  (Thanks to Domen Puncer for the bug report.)
-	- Add MODULE_VERSION() to fs/ntfs/super.c.
-	- Make several functions and variables static.  (Adrian Bunk)
-	- Modify fs/ntfs/aops.c::mark_ntfs_record_dirty() so it allocates
-	  buffers for the page if they are not present and then marks the
-	  buffers belonging to the ntfs record dirty.  This causes the buffers
-	  to become busy and hence they are safe from removal until the page
-	  has been written out.
-	- Fix stupid bug in fs/ntfs/attrib.c::ntfs_external_attr_find() in the
-	  error handling code path that resulted in a BUG() due to trying to
-	  unmap an extent mft record when the mapping of it had failed and it
-	  thus was not mapped.  (Thanks to Ken MacFerrin for the bug report.)
-	- Drop the runlist lock after the vcn has been read in
-	  fs/ntfs/lcnalloc.c::__ntfs_cluster_free().
-	- Rewrite handling of multi sector transfer errors.  We now do not set
-	  PageError() when such errors are detected in the async i/o handler
-	  fs/ntfs/aops.c::ntfs_end_buffer_async_read().  All users of mst
-	  protected attributes now check the magic of each ntfs record as they
-	  use it and act appropriately.  This has the effect of making errors
-	  granular per ntfs record rather than per page which solves the case
-	  where we cannot access any of the ntfs records in a page when a
-	  single one of them had an mst error.  (Thanks to Ken MacFerrin for
-	  the bug report.)
-	- Fix error handling in fs/ntfs/quota.c::ntfs_mark_quotas_out_of_date()
-	  where we failed to release i_mutex on the $Quota/$Q attribute inode.
-	- Fix bug in handling of bad inodes in fs/ntfs/namei.c::ntfs_lookup().
-	- Add mapping of unmapped buffers to all remaining code paths, i.e.
-	  fs/ntfs/aops.c::ntfs_write_mst_block(), mft.c::ntfs_sync_mft_mirror(),
-	  and write_mft_record_nolock().  From now on we require that the
-	  complete runlist for the mft mirror is always mapped into memory.
-	- Add creation of buffers to fs/ntfs/mft.c::ntfs_sync_mft_mirror().
-	- Improve error handling in fs/ntfs/aops.c::ntfs_{read,write}_block().
-	- Cleanup fs/ntfs/aops.c::ntfs_{read,write}page() since we know that a
-	  resident attribute will be smaller than a page which makes the code
-	  simpler.  Also make the code more tolerant to concurrent ->truncate.
-
-2.1.21 - Fix some races and bugs, rewrite mft write code, add mft allocator.
-
-	- Implement extent mft record deallocation
-	  fs/ntfs/mft.c::ntfs_extent_mft_record_free().
-	- Splitt runlist related functions off from attrib.[hc] to runlist.[hc].
-	- Add vol->mft_data_pos and initialize it at mount time.
-	- Rename init_runlist() to ntfs_init_runlist(), ntfs_vcn_to_lcn() to
-	  ntfs_rl_vcn_to_lcn(), decompress_mapping_pairs() to
-	  ntfs_mapping_pairs_decompress(), ntfs_merge_runlists() to
-	  ntfs_runlists_merge() and adapt all callers.
-	- Add fs/ntfs/runlist.[hc]::ntfs_get_nr_significant_bytes(),
-	  ntfs_get_size_for_mapping_pairs(), ntfs_write_significant_bytes(),
-	  and ntfs_mapping_pairs_build(), adapted from libntfs.
-	- Make fs/ntfs/lcnalloc.c::ntfs_cluster_free_from_rl_nolock() not
-	  static and add a declaration for it to lcnalloc.h.
-	- Add fs/ntfs/lcnalloc.h::ntfs_cluster_free_from_rl() which is a static
-	  inline wrapper for ntfs_cluster_free_from_rl_nolock() which takes the
-	  cluster bitmap lock for the duration of the call.
-	- Add fs/ntfs/attrib.[hc]::ntfs_attr_record_resize().
-	- Implement the equivalent of memset() for an ntfs attribute in
-	  fs/ntfs/attrib.[hc]::ntfs_attr_set() and switch
-	  fs/ntfs/logfile.c::ntfs_empty_logfile() to using it.
-	- Remove unnecessary casts from LCN_* constants.
-	- Implement fs/ntfs/runlist.c::ntfs_rl_truncate_nolock().
-	- Add MFT_RECORD_OLD as a copy of MFT_RECORD in fs/ntfs/layout.h and
-	  change MFT_RECORD to contain the NTFS 3.1+ specific fields.
-	- Add a helper function fs/ntfs/aops.c::mark_ntfs_record_dirty() which
-	  marks all buffers belonging to an ntfs record dirty, followed by
-	  marking the page the ntfs record is in dirty and also marking the vfs
-	  inode containing the ntfs record dirty (I_DIRTY_PAGES).
-	- Switch fs/ntfs/index.h::ntfs_index_entry_mark_dirty() to using the
-	  new helper fs/ntfs/aops.c::mark_ntfs_record_dirty() and remove the no
-	  longer needed fs/ntfs/index.[hc]::__ntfs_index_entry_mark_dirty().
-	- Move ntfs_{un,}map_page() from ntfs.h to aops.h and fix resulting
-	  include errors.
-	- Move the typedefs for runlist_element and runlist from types.h to
-	  runlist.h and fix resulting include errors.
-	- Remove unused {__,}format_mft_record() from fs/ntfs/mft.c.
-	- Modify fs/ntfs/mft.c::__mark_mft_record_dirty() to use the helper
-	  mark_ntfs_record_dirty() which also changes the behaviour in that we
-	  now set the buffers belonging to the mft record dirty as well as the
-	  page itself.
-	- Update fs/ntfs/mft.c::write_mft_record_nolock() and sync_mft_mirror()
-	  to cope with the fact that there now are dirty buffers in mft pages.
-	- Update fs/ntfs/inode.c::ntfs_write_inode() to also use the helper
-	  mark_ntfs_record_dirty() and thus to set the buffers belonging to the
-	  mft record dirty as well as the page itself.
-	- Fix compiler warnings on x86-64 in fs/ntfs/dir.c.  (Randy Dunlap,
-	  slightly modified by me)
-	- Add fs/ntfs/mft.c::try_map_mft_record() which fails with -EALREADY if
-	  the mft record is already locked and otherwise behaves the same way
-	  as fs/ntfs/mft.c::map_mft_record().
-	- Modify fs/ntfs/mft.c::write_mft_record_nolock() so that it only
-	  writes the mft record if the buffers belonging to it are dirty.
-	  Otherwise we assume that it was written out by other means already.
-	- Attempting to write outside initialized size is _not_ a bug so remove
-	  the bug check from fs/ntfs/aops.c::ntfs_write_mst_block().  It is in
-	  fact required to write outside initialized size when preparing to
-	  extend the initialized size.
-	- Map the page instead of using page_address() before writing to it in
-	  fs/ntfs/aops.c::ntfs_mft_writepage().
-	- Provide exclusion between opening an inode / mapping an mft record
-	  and accessing the mft record in fs/ntfs/mft.c::ntfs_mft_writepage()
-	  by setting the page not uptodate throughout ntfs_mft_writepage().
-	- Clear the page uptodate flag in fs/ntfs/aops.c::ntfs_write_mst_block()
-	  to ensure noone can see the page whilst the mst fixups are applied.
-	- Add the helper fs/ntfs/mft.c::ntfs_may_write_mft_record() which
-	  checks if an mft record may be written out safely obtaining any
-	  necessary locks in the process.  This is used by
-	  fs/ntfs/aops.c::ntfs_write_mst_block().
-	- Modify fs/ntfs/aops.c::ntfs_write_mst_block() to also work for
-	  writing mft records and improve its error handling in the process.
-	  Now if any of the records in the page fail to be written out, all
-	  other records will be written out instead of aborting completely.
-	- Remove ntfs_mft_aops and update all users to use ntfs_mst_aops.
-	- Modify fs/ntfs/inode.c::ntfs_read_locked_inode() to set the
-	  ntfs_mst_aops for all inodes which are NInoMstProtected() and
-	  ntfs_aops for all other inodes.
-	- Rename fs/ntfs/mft.c::sync_mft_mirror{,_umount}() to
-	  ntfs_sync_mft_mirror{,_umount}() and change their parameters so they
-	  no longer require an ntfs inode to be present.  Update all callers.
-	- Cleanup the error handling in fs/ntfs/mft.c::ntfs_sync_mft_mirror().
-	- Clear the page uptodate flag in fs/ntfs/mft.c::ntfs_sync_mft_mirror()
-	  to ensure noone can see the page whilst the mst fixups are applied.
-	- Remove the no longer needed fs/ntfs/mft.c::ntfs_mft_writepage() and
-	  fs/ntfs/mft.c::try_map_mft_record().
-	- Fix callers of fs/ntfs/aops.c::mark_ntfs_record_dirty() to call it
-	  with the ntfs inode which contains the page rather than the ntfs
-	  inode the mft record of which is in the page.
-	- Fix race condition in fs/ntfs/inode.c::ntfs_put_inode() by moving the
-	  index inode bitmap inode release code from there to
-	  fs/ntfs/inode.c::ntfs_clear_big_inode().  (Thanks to Christoph
-	  Hellwig for spotting this.)
-	- Fix race condition in fs/ntfs/inode.c::ntfs_put_inode() by taking the
-	  inode semaphore around the code that sets ni->itype.index.bmp_ino to
-	  NULL and reorganize the code to optimize it a bit.  (Thanks to
-	  Christoph Hellwig for spotting this.)
-	- Modify fs/ntfs/aops.c::mark_ntfs_record_dirty() to no longer take the
-	  ntfs inode as a parameter as this is confusing and misleading and the
-	  needed ntfs inode is available via NTFS_I(page->mapping->host).
-	  Adapt all callers to this change.
-	- Modify fs/ntfs/mft.c::write_mft_record_nolock() and
-	  fs/ntfs/aops.c::ntfs_write_mst_block() to only check the dirty state
-	  of the first buffer in a record and to take this as the ntfs record
-	  dirty state.  We cannot look at the dirty state for subsequent
-	  buffers because we might be racing with
-	  fs/ntfs/aops.c::mark_ntfs_record_dirty().
-	- Move the static inline ntfs_init_big_inode() from fs/ntfs/inode.c to
-	  inode.h and make fs/ntfs/inode.c::__ntfs_init_inode() non-static and
-	  add a declaration for it to inode.h.  Fix some compilation issues
-	  that resulted due to #includes and header file interdependencies.
-	- Simplify setup of i_mode in fs/ntfs/inode.c::ntfs_read_locked_inode().
-	- Add helpers fs/ntfs/layout.h::MK_MREF() and MK_LE_MREF().
-	- Modify fs/ntfs/mft.c::map_extent_mft_record() to only verify the mft
-	  record sequence number if it is specified (i.e. not zero).
-	- Add fs/ntfs/mft.[hc]::ntfs_mft_record_alloc() and various helper
-	  functions used by it.
-	- Update Documentation/filesystems/ntfs.txt with instructions on how to
-	  use the Device-Mapper driver with NTFS ftdisk/LDM raid.  This removes
-	  the linear raid problem with the Software RAID / MD driver when one
-	  or more of the devices has an odd number of sectors.
-
-2.1.20 - Fix two stupid bugs introduced in 2.1.18 release.
-
-	- Fix stupid bug in fs/ntfs/attrib.c::ntfs_attr_reinit_search_ctx()
-	  where we did not clear ctx->al_entry but it was still set due to
-	  changes in ntfs_attr_lookup() and ntfs_external_attr_find() in
-	  particular.
-	- Fix another stupid bug in fs/ntfs/attrib.c::ntfs_external_attr_find()
-	  where we forgot to unmap the extent mft record when we had finished
-	  enumerating an attribute which caused a bug check to trigger when the
-	  VFS calls ->clear_inode.
-
-2.1.19 - Many cleanups, improvements, and a minor bug fix.
-
-	- Update ->setattr (fs/ntfs/inode.c::ntfs_setattr()) to refuse to
-	  change the uid, gid, and mode of an inode as we do not support NTFS
-	  ACLs yet.
-	- Remove BKL use from ntfs_setattr() syncing up with the rest of the
-	  kernel.
-	- Get rid of the ugly transparent union in fs/ntfs/dir.c::ntfs_readdir()
-	  and ntfs_filldir() as per suggestion from Al Viro.
-	- Change '\0' and L'\0' to simply 0 as per advice from Linus Torvalds.
-	- Update ->truncate (fs/ntfs/inode.c::ntfs_truncate()) to check if the
-	  inode size has changed and to only output an error if so.
-	- Rename fs/ntfs/attrib.h::attribute_value_length() to ntfs_attr_size().
-	- Add le{16,32,64} as well as sle{16,32,64} data types to
-	  fs/ntfs/types.h.
-	- Change ntfschar to be le16 instead of u16 in fs/ntfs/types.h.
-	- Add le versions of VCN, LCN, and LSN called leVCN, leLCN, and leLSN,
-	  respectively, to fs/ntfs/types.h.
-	- Update endianness conversion macros in fs/ntfs/endian.h to use the
-	  new types as appropriate.
-	- Do proper type casting when using sle64_to_cpup() in fs/ntfs/dir.c
-	  and index.c.
-	- Add leMFT_REF data type to fs/ntfs/layout.h.
-	- Update all NTFS header files with the new little endian data types.
-	  Affected files are fs/ntfs/layout.h, logfile.h, and time.h.
-	- Do proper type casting when using ntfs_is_*_recordp() in
-	  fs/ntfs/logfile.c, mft.c, and super.c. 
-	- Fix all the sparse bitwise warnings.  Had to change all the typedef
-	  enums storing little endian values to simple enums plus a typedef for
-	  the datatype to make sparse happy.
-	- Fix a bug found by the new sparse bitwise warnings where the default
-	  upcase table was defined as a pointer to wchar_t rather than ntfschar
-	  in fs/ntfs/ntfs.h and super.c.
-	- Change {const_,}cpu_to_le{16,32}(0) to just 0 as suggested by Al Viro.
-
-2.1.18 - Fix scheduling latencies at mount time as well as an endianness bug.
-
-	- Remove vol->nr_mft_records as it was pretty meaningless and optimize
-	  the calculation of total/free inodes as used by statfs().
-	- Fix scheduling latencies in ntfs_fill_super() by dropping the BKL
-	  because the code itself is using the ntfs_lock semaphore which
-	  provides safe locking.  (Ingo Molnar)
-	- Fix a potential bug in fs/ntfs/mft.c::map_extent_mft_record() that
-	  could occur in the future for when we start closing/freeing extent
-	  inodes if we don't set base_ni->ext.extent_ntfs_inos to NULL after
-	  we free it.
-	- Rename {find,lookup}_attr() to ntfs_attr_{find,lookup}() as well as
-	  find_external_attr() to ntfs_external_attr_find() to cleanup the
-	  namespace a bit and to be more consistent with libntfs.
-	- Rename {{re,}init,get,put}_attr_search_ctx() to
-	  ntfs_attr_{{re,}init,get,put}_search_ctx() as well as the type
-	  attr_search_context to ntfs_attr_search_ctx.
-	- Force use of ntfs_attr_find() in ntfs_attr_lookup() when searching
-	  for the attribute list attribute itself.
-	- Fix endianness bug in ntfs_external_attr_find().
-	- Change ntfs_{external_,}attr_find() to return 0 on success, -ENOENT
-	  if the attribute is not found, and -EIO on real error.  In the case
-	  of -ENOENT, the search context is updated to describe the attribute
-	  before which the attribute being searched for would need to be
-	  inserted if such an action were to be desired and in the case of
-	  ntfs_external_attr_find() the search context is also updated to
-	  indicate the attribute list entry before which the attribute list
-	  entry of the attribute being searched for would need to be inserted
-	  if such an action were to be desired.  Also make ntfs_find_attr()
-	  static and remove its prototype from attrib.h as it is not used
-	  anywhere other than attrib.c.  Update ntfs_attr_lookup() and all
-	  callers of ntfs_{external,}attr_{find,lookup}() for the new return
-	  values.
-	- Minor cleanup of fs/ntfs/inode.c::ntfs_init_locked_inode().
-
-2.1.17 - Fix bugs in mount time error code paths and other updates.
-
-	- Implement bitmap modification code (fs/ntfs/bitmap.[hc]).  This
-	  includes functions to set/clear a single bit or a run of bits.
-	- Add fs/ntfs/attrib.[hc]::ntfs_find_vcn() which returns the locked
-	  runlist element containing a particular vcn.  It also takes care of
-	  mapping any needed runlist fragments.
-	- Implement cluster (de-)allocation code (fs/ntfs/lcnalloc.[hc]).
-	- Load attribute definition table from $AttrDef at mount time.
-	- Fix bugs in mount time error code paths involving (de)allocation of
-	  the default and volume upcase tables.
-	- Remove ntfs_nr_mounts as it is no longer used.
-
-2.1.16 - Implement access time updates, file sync, async io, and read/writev.
-
-	- Add support for readv/writev and aio_read/aio_write (fs/ntfs/file.c).
-	  This is done by setting the appropriate file operations pointers to
-	  the generic helper functions provided by mm/filemap.c.
-	- Implement fsync, fdatasync, and msync both for files (fs/ntfs/file.c)
-	  and directories (fs/ntfs/dir.c).
-	- Add support for {a,m,c}time updates to inode.c::ntfs_write_inode().
-	  Note, except for the root directory and any other system files opened
-	  by the user, the system files will not have their access times
-	  updated as they are only accessed at the inode level an hence the
-	  file level functions which cause the times to be updated are never
-	  invoked.
-
-2.1.15 - Invalidate quotas when (re)mounting read-write.
-
-	- Add new element itype.index.collation_rule to the ntfs inode
-	  structure and set it appropriately in ntfs_read_locked_inode().
-	- Implement a new inode type "index" to allow efficient access to the
-	  indices found in various system files and adapt inode handling
-	  accordingly (fs/ntfs/inode.[hc]).  An index inode is essentially an
-	  attribute inode (NInoAttr() is true) with an attribute type of
-	  AT_INDEX_ALLOCATION.  As such, it is no longer allowed to call
-	  ntfs_attr_iget() with an attribute type of AT_INDEX_ALLOCATION as
-	  there would be no way to distinguish between normal attribute inodes
-	  and index inodes.  The function to obtain an index inode is
-	  ntfs_index_iget() and it uses the helper function
-	  ntfs_read_locked_index_inode().  Note, we do not overload
-	  ntfs_attr_iget() as indices consist of multiple attributes so using
-	  ntfs_attr_iget() to obtain an index inode would be confusing.
-	- Ensure that there is no overflow when doing page->index <<
-	  PAGE_CACHE_SHIFT by casting page->index to s64 in fs/ntfs/aops.c.
-	- Use atomic kmap instead of kmap() in fs/ntfs/aops.c::ntfs_read_page()
-	  and ntfs_read_block().
-	- Use case sensitive attribute lookups instead of case insensitive ones.
-	- Lock all page cache pages belonging to mst protected attributes while
-	  accessing them to ensure we never see corrupt data while the page is
-	  under writeout.
-	- Add framework for generic ntfs collation (fs/ntfs/collation.[hc]).
-	  We have ntfs_is_collation_rule_supported() to check if the collation
-	  rule you want to use is supported and ntfs_collation() which actually
-	  collates two data items.  We currently only support COLLATION_BINARY
-	  and COLLATION_NTOFS_ULONG but support for other collation rules will
-	  be added as the need arises.
-	- Add a new type, ntfs_index_context, to allow retrieval of an index
-	  entry using the corresponding index key.  To get an index context,
-	  use ntfs_index_ctx_get() and to release it, use ntfs_index_ctx_put().
-	  This also adds a new slab cache for the index contexts.  To lookup a
-	  key in an index inode, use ntfs_index_lookup().  After modifying an
-	  index entry, call ntfs_index_entry_flush_dcache_page() followed by
-	  ntfs_index_entry_mark_dirty() to ensure the changes are written out
-	  to disk.  For details see fs/ntfs/index.[hc].  Note, at present, if
-	  an index entry is in the index allocation attribute rather than the
-	  index root attribute it will not be written out (you will get a
-	  warning message about discarded changes instead).
-	- Load the quota file ($Quota) and check if quota tracking is enabled
-	  and if so, mark the quotas out of date.  This causes windows to
-	  rescan the volume on boot and update all quota entries.
-	- Add a set_page_dirty address space operation for ntfs_m[fs]t_aops.
-	  It is simply set to __set_page_dirty_nobuffers() to make sure that
-	  running set_page_dirty() on a page containing mft/ntfs records will
-	  not affect the dirty state of the page buffers.
-	- Add fs/ntfs/index.c::__ntfs_index_entry_mark_dirty() which sets all
-	  buffers that are inside the ntfs record in the page dirty after which
-	  it sets the page dirty.  This allows ->writepage to only write the
-	  dirty index records rather than having to write all the records in
-	  the page.  Modify fs/ntfs/index.h::ntfs_index_entry_mark_dirty() to
-	  use this rather than __set_page_dirty_nobuffers().
-	- Implement fs/ntfs/aops.c::ntfs_write_mst_block() which enables the
-	  writing of page cache pages belonging to mst protected attributes
-	  like the index allocation attribute in directory indices and other
-	  indices like $Quota/$Q, etc.  This means that the quota is now marked
-	  out of date on all volumes rather than only on ones where the quota
-	  defaults entry is in the index root attribute of the $Quota/$Q index.
-
-2.1.14 - Fix an NFSd caused deadlock reported by several users.
-
-	- Modify fs/ntfs/ntfs_readdir() to copy the index root attribute value
-	  to a buffer so that we can put the search context and unmap the mft
-	  record before calling the filldir() callback.  We need to do this
-	  because of NFSd which calls ->lookup() from its filldir callback()
-	  and this causes NTFS to deadlock as ntfs_lookup() maps the mft record
-	  of the directory and since ntfs_readdir() has got it mapped already
-	  ntfs_lookup() deadlocks.
-
-2.1.13 - Enable overwriting of resident files and housekeeping of system files.
-
-	- Implement writing of mft records (fs/ntfs/mft.[hc]), which includes
-	  keeping the mft mirror in sync with the mft when mirrored mft records
-	  are written.  The functions are write_mft_record{,_nolock}().  The
-	  implementation is quite rudimentary for now with lots of things not
-	  implemented yet but I am not sure any of them can actually occur so
-	  I will wait for people to hit each one and only then implement it.
-	- Commit open system inodes at umount time.  This should make it
-	  virtually impossible for sync_mft_mirror_umount() to ever be needed.
-	- Implement ->write_inode (fs/ntfs/inode.c::ntfs_write_inode()) for the
-	  ntfs super operations.  This gives us inode writing via the VFS inode
-	  dirty code paths.  Note:  Access time updates are not implemented yet.
-	- Implement fs/ntfs/mft.[hc]::{,__}mark_mft_record_dirty() and make
-	  fs/ntfs/aops.c::ntfs_writepage() and ntfs_commit_write() use it, thus
-	  finally enabling resident file overwrite!  (-8  This also includes a
-	  placeholder for ->writepage (ntfs_mft_writepage()), which for now
-	  just redirties the page and returns.  Also, at umount time, we for
-	  now throw away all mft data page cache pages after the last call to
-	  ntfs_commit_inode() in the hope that all inodes will have been
-	  written out by then and hence no dirty (meta)data will be lost.  We
-	  also check for this case and emit an error message telling the user
-	  to run chkdsk.
-	- Use set_page_writeback() and end_page_writeback() in the resident
-	  attribute code path of fs/ntfs/aops.c::ntfs_writepage() otherwise
-	  the radix-tree tag PAGECACHE_TAG_DIRTY remains set even though the
-	  page is clean.
-	- Implement ntfs_mft_writepage() so it now checks if any of the mft
-	  records in the page are dirty and if so redirties the page and
-	  returns.  Otherwise it just returns (after doing set_page_writeback(),
-	  unlock_page(), end_page_writeback() or the radix-tree tag
-	  PAGECACHE_TAG_DIRTY remains set even though the page is clean), thus
-	  alowing the VM to do with the page as it pleases.  Also, at umount
-	  time, now only throw away dirty mft (meta)data pages if dirty inodes
-	  are present and ask the user to email us if they see this happening.
-	- Add functions ntfs_{clear,set}_volume_flags(), to modify the volume
-	  information flags (fs/ntfs/super.c).
-	- Mark the volume dirty when (re)mounting read-write and mark it clean
-	  when unmounting or remounting read-only.  If any volume errors are
-	  found, the volume is left marked dirty to force chkdsk to run.
-	- Add code to set the NT4 compatibility flag when (re)mounting
-	  read-write for newer NTFS versions but leave it commented out for now
-	  since we do not make any modifications that are NTFS 1.2 specific yet
-	  and since setting this flag breaks Captive-NTFS which is not nice.
-	  This code must be enabled once we start writing NTFS 1.2 specific
-	  changes otherwise Windows NTFS driver might crash / cause corruption.
-
-2.1.12 - Fix the second fix to the decompression engine and some cleanups.
-
-	- Add a new address space operations struct, ntfs_mst_aops, for mst
-	  protected attributes.  This is because the default ntfs_aops do not
-	  make sense with mst protected data and were they to write anything to
-	  such an attribute they would cause data corruption so we provide
-	  ntfs_mst_aops which does not have any write related operations set.
-	- Cleanup dirty ntfs inode handling (fs/ntfs/inode.[hc]) which also
-	  includes an adapted ntfs_commit_inode() and an implementation of
-	  ntfs_write_inode() which for now just cleans dirty inodes without
-	  writing them (it does emit a warning that this is happening).
-	- Undo the second decompression engine fix (see 2.1.9 release ChangeLog
-	  entry) as it was only fixing a theoretical bug but at the same time
-	  it badly broke the handling of sparse and uncompressed compression
-	  blocks.
-
-2.1.11 - Driver internal cleanups.
-
-	- Only build logfile.o if building the driver with read-write support.
-	- Really final white space cleanups.
-	- Use generic_ffs() instead of ffs() in logfile.c which allows the
-	  log_page_size variable to be optimized by gcc into a constant.
-	- Rename uchar_t to ntfschar everywhere as uchar_t is unsigned 1-byte
-	  char as defined by POSIX and as found on some systems.
-
-2.1.10 - Force read-only (re)mounting of volumes with unsupported volume flags.
-
-	- Finish off the white space cleanups (remove trailing spaces, etc).
-	- Clean up ntfs_fill_super() and ntfs_read_inode_mount() by removing
-	  the kludges around the first iget().  Instead of (re)setting ->s_op
-	  we have the $MFT inode set up by explicit new_inode() / set ->i_ino /
-	  insert_inode_hash() / call ntfs_read_inode_mount() directly.  This
-	  kills the need for second super_operations and allows to return error
-	  from ntfs_read_inode_mount() without resorting to ugly "poisoning"
-	  tricks.  (Al Viro)
-	- Force read-only (re)mounting if any of the following bits are set in
-	  the volume information flags:
-	  	VOLUME_IS_DIRTY, VOLUME_RESIZE_LOG_FILE,
-		VOLUME_UPGRADE_ON_MOUNT, VOLUME_DELETE_USN_UNDERWAY,
-		VOLUME_REPAIR_OBJECT_ID, VOLUME_MODIFIED_BY_CHKDSK
-	  To make this easier we define VOLUME_MUST_MOUNT_RO_MASK with all the
-	  above bits set so the test is made easy.
-
-2.1.9 - Fix two bugs in decompression engine.
-
-	- Fix a bug where we would not always detect that we have reached the
-	  end of a compression block because we were ending at minus one byte
-	  which is effectively the same as being at the end.  The fix is to
-	  check whether the uncompressed buffer has been fully filled and if so
-	  we assume we have reached the end of the compression block.  A big
-	  thank you to Marcin Gibuła for the bug report, the assistance in
-	  tracking down the bug and testing the fix.
-	- Fix a possible bug where when a compressed read is truncated to the
-	  end of the file, the offset inside the last page was not truncated.
-
-2.1.8 - Handle $MFT mirror and $LogFile, improve time handling, and cleanups.
-
-	- Use get_bh() instead of manual atomic_inc() in fs/ntfs/compress.c.
-	- Modify fs/ntfs/time.c::ntfs2utc(), get_current_ntfs_time(), and
-	  utc2ntfs() to work with struct timespec instead of time_t on the
-	  Linux UTC time side thus preserving the full precision of the NTFS
-	  time and only loosing up to 99 nano-seconds in the Linux UTC time.
-	- Move fs/ntfs/time.c to fs/ntfs/time.h and make the time functions
-	  static inline.
-	- Remove unused ntfs_dirty_inode().
-	- Cleanup super operations declaration in fs/ntfs/super.c.
-	- Wrap flush_dcache_mft_record_page() in #ifdef NTFS_RW.
-	- Add NInoTestSetFoo() and NInoTestClearFoo() macro magic to
-	  fs/ntfs/inode.h and use it to declare NInoTest{Set,Clear}Dirty.
-	- Move typedefs for ntfs_attr and test_t from fs/ntfs/inode.c to
-	  fs/ntfs/inode.h so they can be used elsewhere.
-	- Determine the mft mirror size as the number of mirrored mft records
-	  and store it in ntfs_volume->mftmirr_size (fs/ntfs/super.c).
-	- Load the mft mirror at mount time and compare the mft records stored
-	  in it to the ones in the mft.  Force a read-only mount if the two do
-	  not match (fs/ntfs/super.c).
-	- Fix type casting related warnings on 64-bit architectures.  Thanks
-	  to Meelis Roos for reporting them.
-	- Move %L to %ll as %L is floating point and %ll is integer which is
-	  what we want.
-	- Read the journal ($LogFile) and determine if the volume has been
-	  shutdown cleanly and force a read-only mount if not (fs/ntfs/super.c
-	  and fs/ntfs/logfile.c).  This is a little bit of a crude check in
-	  that we only look at the restart areas and not at the actual log
-	  records so that there will be a very small number of cases where we
-	  think that a volume is dirty when in fact it is clean.  This should
-	  only affect volumes that have not been shutdown cleanly and did not
-	  have any pending, non-check-pointed i/o.
-	- If the $LogFile indicates a clean shutdown and a read-write (re)mount
-	  is requested, empty $LogFile by overwriting it with 0xff bytes to
-	  ensure that Windows cannot cause data corruption by replaying a stale
-	  journal after Linux has written to the volume.
-
-2.1.7 - Enable NFS exporting of mounted NTFS volumes.
-
-	- Set i_generation in the VFS inode from the seq_no of the NTFS inode.
-	- Make ntfs_lookup() NFS export safe, i.e. use d_splice_alias(), etc.
-	- Implement ->get_dentry() in fs/ntfs/namei.c::ntfs_get_dentry() as the
-	  default doesn't allow inode number 0 which is a valid inode on NTFS
-	  and even if it did allow that it uses iget() instead of ntfs_iget()
-	  which makes it useless for us.
-	- Implement ->get_parent() in fs/ntfs/namei.c::ntfs_get_parent() as the
-	  default just returns -EACCES which is not very useful.
-	- Define export operations (->s_export_op) for NTFS (ntfs_export_ops)
-	  and set them up in the super block at mount time (super.c) this
-	  allows mounted NTFS volumes to be exported via NFS.
-	- Add missing return -EOPNOTSUPP; in
-	  fs/ntfs/aops.c::ntfs_commit_nonresident_write().
-	- Enforce no atime and no dir atime updates at mount/remount time as
-	  they are not implemented yet anyway.
-	- Move a few assignments in fs/ntfs/attrib.c::load_attribute_list() to
-	  after a NULL check.  Thanks to Dave Jones for pointing this out.
-
-2.1.6 - Fix minor bug in handling of compressed directories.
-
-	- Fix bug in handling of compressed directories.  A compressed
-	  directory is not really compressed so when we set the ->i_blocks
-	  field of a compressed directory inode we were setting it from the
-	  non-existing field ni->itype.compressed.size which gave random
-	  results...  For directories we now always use ni->allocated_size.
-
-2.1.5 - Fix minor bug in attribute list attribute handling.
-
-	- Fix bug in attribute list handling.  Actually it is not as much a bug
-	  as too much protection in that we were not allowing attribute lists
-	  which waste space on disk while Windows XP clearly allows it and in
-	  fact creates such attribute lists so our driver was failing.
-	- Update NTFS documentation ready for 2.6 kernel release.
-
-2.1.4 - Reduce compiler requirements.
-
-	- Remove all uses of unnamed structs and unions in the driver to make
-	  old and newer gcc versions happy. Makes it a bit uglier IMO but at
-	  least people will stop hassling me about it.
-
-2.1.3 - Important bug fixes in corner cases.
-
-	- super.c::parse_ntfs_boot_sector(): Correct the check for 64-bit
-	  clusters. (Philipp Thomas)
-	- attrib.c::load_attribute_list(): Fix bug when initialized_size is a
-	  multiple of the block_size but not the cluster size. (Szabolcs
-	  Szakacsits)
-
-2.1.2 - Important bug fixes aleviating the hangs in statfs.
-
-	- Fix buggy free cluster and free inode determination logic.
-
-2.1.1 - Minor updates.
-
-	- Add handling for initialized_size != data_size in compressed files.
-	- Reduce function local stack usage from 0x3d4 bytes to just noise in
-	  fs/ntfs/upcase.c. (Randy Dunlap)
-	- Remove compiler warnings for newer gcc.
-	- Pages are no longer kmapped by mm/filemap.c::generic_file_write()
-	  around calls to ->{prepare,commit}_write.  Adapt NTFS appropriately
-	  in fs/ntfs/aops.c::ntfs_prepare_nonresident_write() by using
-	  kmap_atomic(KM_USER0).
-
-2.1.0 - First steps towards write support: implement file overwrite.
-
-	- Add configuration option for developmental write support with an
-	  appropriately scary configuration help text.
-	- Initial implementation of fs/ntfs/aops.c::ntfs_writepage() and its
-	  helper fs/ntfs/aops.c::ntfs_write_block(). This enables mmap(2) based
-	  overwriting of existing files on ntfs. Note: Resident files are
-	  only written into memory, and not written out to disk at present, so
-	  avoid writing to files smaller than about 1kiB.
-	- Initial implementation of fs/ntfs/aops.c::ntfs_prepare_write(), its
-	  helper fs/ntfs/aops.c::ntfs_prepare_nonresident_write() and their
-	  counterparts, fs/ntfs/aops.c::ntfs_commit_write(), and
-	  fs/ntfs/aops.c::ntfs_commit_nonresident_write(), respectively. Also,
-	  add generic_file_write() to the ntfs file operations (fs/ntfs/file.c).
-	  This enables write(2) based overwriting of existing files on ntfs.
-	  Note: As with mmap(2) based overwriting, resident files are only
-	  written into memory, and not written out to disk at present, so avoid
-	  writing to files smaller than about 1kiB.
-	- Implement ->truncate (fs/ntfs/inode.c::ntfs_truncate()) and
-	  ->setattr() (fs/ntfs/inode.c::ntfs_setattr()) inode operations for
-	  files with the purpose of intercepting and aborting all i_size
-	  changes which we do not support yet. ntfs_truncate() actually only
-	  emits a warning message but AFAICS our interception of i_size changes
-	  elsewhere means ntfs_truncate() never gets called for i_size changes.
-	  It is only called from generic_file_write() when we fail in
-	  ntfs_prepare_{,nonresident_}write() in order to discard any
-	  instantiated buffers beyond i_size. Thus i_size is not actually
-	  changed so our warning message is enough. Unfortunately it is not
-	  possible to easily determine if i_size is being changed or not hence
-	  we just emit an appropriately worded error message.
-
-2.0.25 - Small bug fixes and cleanups.
-
-	- Unlock the page in an out of memory error code path in
-	  fs/ntfs/aops.c::ntfs_read_block().
-	- If fs/ntfs/aops.c::ntfs_read_page() is called on an uptodate page,
-	  just unlock the page and return. (This can happen due to ->writepage
-	  clearing PageUptodate() during write out of MstProtected()
-	  attributes.
-	- Remove leaked write code again.
-
-2.0.24 - Cleanups.
-
-	- Treat BUG_ON() as ASSERT() not VERIFY(), i.e. do not use side effects
-	  inside BUG_ON(). (Adam J. Richter)
-	- Split logical OR expressions inside BUG_ON() into individual BUG_ON()
-	  calls for improved debugging. (Adam J. Richter)
-	- Add errors flag to the ntfs volume state, accessed via
-	  NVol{,Set,Clear}Errors(vol).
-	- Do not allow read-write remounts of read-only volumes with errors.
-	- Clarify comment for ntfs file operation sendfile which was added by
-	  Christoph Hellwig a while ago (just using generic_file_sendfile())
-	  to say that ntfs ->sendfile is only used for the case where the
-	  source data is on the ntfs partition and the destination is
-	  somewhere else, i.e. nothing we need to concern ourselves with.
-	- Add generic_file_write() as our ntfs file write operation.
-
-2.0.23 - Major bug fixes (races, deadlocks, non-i386 architectures).
-
-	- Massive internal locking changes to mft record locking. Fixes lock
-	  recursion and replaces the mrec_lock read/write semaphore with a
-	  mutex. Also removes the now superfluous mft_count. This fixes several
-	  race conditions and deadlocks, especially in the future write code.
-	- Fix ntfs over loopback for compressed files by adding an
-	  optimization barrier. (gcc was screwing up otherwise ?)
-	- Miscellaneous cleanups all over the code and a fix or two in error
-	  handling code paths.
-	Thanks go to Christoph Hellwig for pointing out the following two:
-	- Remove now unused function fs/ntfs/malloc.h::vmalloc_nofs().
-	- Fix ntfs_free() for ia64 and parisc by checking for VMALLOC_END, too.
-
-2.0.22 - Cleanups, mainly to ntfs_readdir(), and use C99 initializers.
-
-	- Change fs/ntfs/dir.c::ntfs_reddir() to only read/write ->f_pos once
-	  at entry/exit respectively.
-	- Use C99 initializers for structures.
-	- Remove unused variable blocks from fs/ntfs/aops.c::ntfs_read_block().
-
-2.0.21 - Check for, and refuse to work with too large files/directories/volumes.
-
-	- Limit volume size at mount time to 2TiB on architectures where
-	  unsigned long is 32-bits (fs/ntfs/super.c::parse_ntfs_boot_sector()).
-	  This is the most we can do without overflowing the 32-bit limit of
-	  the block device size imposed on us by sb_bread() and sb_getblk()
-	  for the time being.
-	- Limit file/directory size at open() time to 16TiB on architectures
-	  where unsigned long is 32-bits (fs/ntfs/file.c::ntfs_file_open() and
-	  fs/ntfs/dir.c::ntfs_dir_open()). This is the most we can do without
-	  overflowing the page cache page index.
-
-2.0.20 - Support non-resident directory index bitmaps, fix page leak in readdir.
-
-	- Move the directory index bitmap to use an attribute inode instead of
-	  having special fields for it inside the ntfs inode structure. This
-	  means that the index bitmaps now use the page cache for i/o, too,
-	  and also as a side effect we get support for non-resident index
-	  bitmaps for free.
-	- Simplify/cleanup error handling in fs/ntfs/dir.c::ntfs_readdir() and
-	  fix a page leak that manifested itself in some cases.
-	- Add fs/ntfs/inode.c::ntfs_put_inode(), which we need to release the
-	  index bitmap inode on the final iput().
-
-2.0.19 - Fix race condition, improvements, and optimizations in i/o interface.
-
-	- Apply block optimization added to fs/ntfs/aops.c::ntfs_read_block()
-	  to fs/ntfs/compress.c::ntfs_file_read_compressed_block() as well.
-	- Drop the "file" from ntfs_file_read_compressed_block().
-	- Rename fs/ntfs/aops.c::ntfs_enb_buffer_read_async() to
-	  ntfs_end_buffer_async_read() (more like the fs/buffer.c counterpart).
-	- Update ntfs_end_buffer_async_read() with the improved logic from
-	  its updated counterpart fs/buffer.c::end_buffer_async_read(). Apply
-	  further logic improvements to better determine when we set PageError.
-	- Update submission of buffers in fs/ntfs/aops.c::ntfs_read_block() to
-	  check for the buffers being uptodate first in line with the updated
-	  fs/buffer.c::block_read_full_page(). This plugs a small race
-	  condition.
-
-2.0.18 - Fix race condition in reading of compressed files.
-
-	- There was a narrow window between checking a buffer head for being
-	  uptodate and locking it in ntfs_file_read_compressed_block(). We now
-	  lock the buffer and then check whether it is uptodate or not.
-
-2.0.17 - Cleanups and optimizations - shrinking the ToDo list.
-
-	- Modify fs/ntfs/inode.c::ntfs_read_locked_inode() to return an error
-	  code and update callers, i.e. ntfs_iget(), to pass that error code
-	  up instead of just using -EIO.
-	- Modifications to super.c to ensure that both mount and remount
-	  cannot set any write related options when the driver is compiled
-	  read-only.
-	- Optimize block resolution in fs/ntfs/aops.c::ntfs_read_block() to
-	  cache the current runlist element. This should improve performance
-	  when reading very large and/or very fragmented data.
-
-2.0.16 - Convert access to $MFT/$BITMAP to attribute inode API.
-
-	- Fix a stupid bug introduced in 2.0.15 where we were unmapping the
-	  wrong inode in fs/ntfs/inode.c::ntfs_attr_iget().
-	- Fix debugging check in fs/ntfs/aops.c::ntfs_read_block().
-	- Convert $MFT/$BITMAP access to attribute inode API and remove all
-	  remnants of the ugly mftbmp address space and operations hack. This
-	  means we finally have only one readpage function as well as only one
-	  async io completion handler. Yey! The mft bitmap is now just an
-	  attribute inode and is accessed from vol->mftbmp_ino just as if it
-	  were a normal file. Fake inodes rule. (-:
-
-2.0.15 - Fake inodes based attribute i/o via the pagecache, fixes and cleanups.
-
-	- Fix silly bug in fs/ntfs/super.c::parse_options() which was causing
-	  remounts to fail when the partition had an entry in /etc/fstab and
-	  the entry specified the nls= option.
-	- Apply same macro magic used in fs/ntfs/inode.h to fs/ntfs/volume.h to
-	  expand all the helper functions NVolFoo(), NVolSetFoo(), and
-	  NVolClearFoo().
-	- Move copyright statement from driver initialisation message to
-	  module description (fs/super.c). This makes the initialisation
-	  message fit on one line and fits in better with rest of kernel.
-	- Update fs/ntfs/attrib.c::map_run_list() to work on both real and
-	  attribute inodes, and both for files and directories.
-	- Implement fake attribute inodes allowing all attribute i/o to go via
-	  the page cache and to use all the normal vfs/mm functionality:
-	  - Add ntfs_attr_iget() and its helper ntfs_read_locked_attr_inode()
-	    to fs/ntfs/inode.c.
-	  - Add needed cleanup code to ntfs_clear_big_inode().
-	- Merge address space operations for files and directories (aops.c),
-	  now just have ntfs_aops:
-	  - Rename:
-		end_buffer_read_attr_async() ->	ntfs_end_buffer_read_async(),
-		ntfs_attr_read_block()	     ->	ntfs_read_block(),
-		ntfs_file_read_page()	     ->	ntfs_readpage().
-	  - Rewrite fs/ntfs/aops.c::ntfs_readpage() to work on both real and
-	    attribute inodes, and both for files and directories.
-	  - Remove obsolete fs/ntfs/aops.c::ntfs_mst_readpage().
-
-2.0.14 - Run list merging code cleanup, minor locking changes, typo fixes.
-
-	- Change fs/ntfs/super.c::ntfs_statfs() to not rely on BKL by moving
-	  the locking out of super.c::get_nr_free_mft_records() and taking and
-	  dropping the mftbmp_lock rw_semaphore in ntfs_statfs() itself.
-	- Bring attribute runlist merging code (fs/ntfs/attrib.c) in sync with
-	  current userspace ntfs library code. This means that if a merge
-	  fails the original runlists are always left unmodified instead of
-	  being silently corrupted.
-	- Misc typo fixes.
-
-2.0.13 - Use iget5_locked() in preparation for fake inodes and small cleanups.
-
-	- Remove nr_mft_bits and the now superfluous union with nr_mft_records
-	  from ntfs_volume structure.
-	- Remove nr_lcn_bits and the now superfluous union with nr_clusters
-	  from ntfs_volume structure.
-	- Use iget5_locked() and friends instead of conventional iget(). Wrap
-	  the call in fs/ntfs/inode.c::ntfs_iget() and update callers of iget()
-	  to use ntfs_iget(). Leave only one iget() call at mount time so we
-	  don't need an ntfs_iget_mount().
-	- Change fs/ntfs/inode.c::ntfs_new_extent_inode() to take mft_no as an
-	  additional argument.
-
-2.0.12 - Initial cleanup of address space operations following 2.0.11 changes.
-
-	- Merge fs/ntfs/aops.c::end_buffer_read_mst_async() and
-	  fs/ntfs/aops.c::end_buffer_read_file_async() into one function
-	  fs/ntfs/aops.c::end_buffer_read_attr_async() using NInoMstProtected()
-	  to determine whether to apply mst fixups or not.
-	- Above change allows merging fs/ntfs/aops.c::ntfs_file_read_block()
-	  and fs/ntfs/aops.c::ntfs_mst_readpage() into one function
-	  fs/ntfs/aops.c::ntfs_attr_read_block(). Also, create a tiny wrapper
-	  fs/ntfs/aops.c::ntfs_mst_readpage() to transform the parameters from
-	  the VFS readpage function prototype to the ntfs_attr_read_block()
-	  function prototype.
-
-2.0.11 - Initial preparations for fake inode based attribute i/o.
-
-	- Move definition of ntfs_inode_state_bits to fs/ntfs/inode.h and
-	  do some macro magic (adapted from include/linux/buffer_head.h) to
-	  expand all the helper functions NInoFoo(), NInoSetFoo(), and
-	  NInoClearFoo().
-	- Add new flag to ntfs_inode_state_bits: NI_Sparse.
-	- Add new fields to ntfs_inode structure to allow use of fake inodes
-	  for attribute i/o: type, name, name_len. Also add new state bits:
-	  NI_Attr, which, if set, indicates the inode is a fake inode, and
-	  NI_MstProtected, which, if set, indicates the attribute uses multi
-	  sector transfer protection, i.e. fixups need to be applied after
-	  reads and before/after writes.
-	- Rename fs/ntfs/inode.c::ntfs_{new,clear,destroy}_inode() to
-	  ntfs_{new,clear,destroy}_extent_inode() and update callers.
-	- Use ntfs_clear_extent_inode() in fs/ntfs/inode.c::__ntfs_clear_inode()
-	  instead of ntfs_destroy_extent_inode().
-	- Cleanup memory deallocations in {__,}ntfs_clear_{,big_}inode().
-	- Make all operations on ntfs inode state bits use the NIno* functions.
-	- Set up the new ntfs inode fields and state bits in
-	  fs/ntfs/inode.c::ntfs_read_inode() and add appropriate cleanup of
-	  allocated memory to __ntfs_clear_inode().
-	- Cleanup ntfs_inode structure a bit for better ordering of elements
-	  w.r.t. their size to allow better packing of the structure in memory.
-
-2.0.10 - There can only be 2^32 - 1 inodes on an NTFS volume.
-
-	- Add check at mount time to verify that the number of inodes on the
-	  volume does not exceed 2^32 - 1, which is the maximum allowed for
-	  NTFS according to Microsoft.
-	- Change mft_no member of ntfs_inode structure to be unsigned long.
-	  Update all users. This makes ntfs_inode->mft_no just a copy of struct
-	  inode->i_ino. But we can't just always use struct inode->i_ino and
-	  remove mft_no because extent inodes do not have an attached struct
-	  inode.
-
-2.0.9 - Decompression engine now uses a single buffer and other cleanups.
-
-	- Change decompression engine to use a single buffer protected by a
-	  spin lock instead of per-CPU buffers. (Rusty Russell)
-	- Do not update cb_pos when handling a partial final page during
-	  decompression of a sparse compression block, as the value is later
-	  reset without being read/used. (Rusty Russell)
-	- Switch to using the new KM_BIO_SRC_IRQ for atomic kmap()s. (Andrew
-	  Morton)
-	- Change buffer size in ntfs_readdir()/ntfs_filldir() to use
-	  NLS_MAX_CHARSET_SIZE which makes the buffers almost 1kiB each but
-	  it also makes everything safer so it is a good thing.
-	- Miscellaneous minor cleanups to comments.
-
-2.0.8 - Major updates for handling of case sensitivity and dcache aliasing.
-
-	Big thanks go to Al Viro and other inhabitants of #kernel for investing
-	their time to discuss the case sensitivity and dcache aliasing issues.
-
-	- Remove unused source file fs/ntfs/attraops.c.
-	- Remove show_inodes mount option(s), thus dropping support for
-	  displaying of short file names.
-	- Remove deprecated mount option posix.
-	- Restore show_sys_files mount option.
-	- Add new mount option case_sensitive, to determine if the driver
-	  treats file names as case sensitive or not. If case sensitive, create
-	  file names in the POSIX namespace. Otherwise create file names in the
-	  LONG/WIN32 namespace. Note, files remain accessible via their short
-	  file name, if it exists.
-	- Remove really dumb logic bug in boot sector recovery code.
-	- Fix dcache aliasing issues wrt short/long file names via changes
-	  to fs/ntfs/dir.c::ntfs_lookup_inode_by_name() and
-	  fs/ntfs/namei.c::ntfs_lookup():
-	  - Add additional argument to ntfs_lookup_inode_by_name() in which we
-	    return information about the matching file name if the case is not
-	    matching or the match is a short file name. See comments above the
-	    function definition for details.
-	  - Change ntfs_lookup() to only create dcache entries for the correctly
-	    cased file name and only for the WIN32 namespace counterpart of DOS
-	    namespace file names. This ensures we have only one dentry per
-	    directory and also removes all dcache aliasing issues between short
-	    and long file names once we add write support. See comments above
-	    function for details.
-	- Fix potential 1 byte overflow in fs/ntfs/unistr.c::ntfs_ucstonls().
-
-2.0.7 - Minor cleanups and updates for changes in core kernel code.
-
-	- Remove much of the NULL struct element initializers.
-	- Various updates to make compatible with recent kernels.
-	- Remove defines of MAX_BUF_PER_PAGE and include linux/buffer_head.h
-	  in fs/ntfs/ntfs.h instead.
-	- Remove no longer needed KERNEL_VERSION checks. We are now in the
-	  kernel proper so they are no longer needed.
-
-2.0.6 - Major bugfix to make compatible with other kernel changes.
-
-	- Initialize the mftbmp address space properly now that there are more
-	  fields in the struct address_space. This was leading to hangs and
-	  oopses on umount since 2.5.12 because of changes to other parts of
-	  the kernel. We probably want a kernel generic init_address_space()
-	  function...
-	- Drop BKL from ntfs_readdir() after consultation with Al Viro. The
-	  only caller of ->readdir() is vfs_readdir() which holds i_mutex
-	  during the call, and i_mutex is sufficient protection against changes
-	  in the directory inode (including ->i_size).
-	- Use generic_file_llseek() for directories (as opposed to
-	  default_llseek()) as this downs i_mutex instead of the BKL which is
-	  what we now need for exclusion against ->f_pos changes considering we
-	  no longer take the BKL in ntfs_readdir().
-
-2.0.5 - Major bugfix. Buffer overflow in extent inode handling.
-
-	- No need to set old blocksize in super.c::ntfs_fill_super() as the
-	  VFS does so via invocation of deactivate_super() calling
-	  fs->fill_super() calling block_kill_super() which does it.
-	- BKL moved from VFS into dir.c::ntfs_readdir(). (Linus Torvalds)
-	  -> Do we really need it? I don't think so as we have exclusion on
-	  the directory ntfs_inode rw_semaphore mrec_lock. We mmight have to
-	  move the ->f_pos accesses under the mrec_lock though. Check this...
-	- Fix really, really, really stupid buffer overflow in extent inode
-	  handling in mft.c::map_extent_mft_record().
-
-2.0.4 - Cleanups and updates for kernel 2.5.11.
-
-	- Add documentation on how to use the MD driver to be able to use NTFS
-	  stripe and volume sets in Linux and generally cleanup documentation
-	  a bit.
-	Remove all uses of kdev_t in favour of struct block_device *:
-	- Change compress.c::ntfs_file_read_compressed_block() to use
-	  sb_getblk() instead of getblk().
-	- Change super.c::ntfs_fill_super() to use bdev_hardsect_size() instead
-	  of get_hardsect_size().
-	- No need to get old blocksize in super.c::ntfs_fill_super() as
-	  fs/super.c::get_sb_bdev() already does this.
-	- Set bh->b_bdev instead of bh->b_dev throughout aops.c.
-
-2.0.3 - Small bug fixes, cleanups, and performance improvements.
-
-	- Remove some dead code from mft.c.
-	- Optimize readpage and read_block functions throughout aops.c so that
-	  only initialized blocks are read. Non-initialized ones have their
-	  buffer head mapped, zeroed, and set up to date, without scheduling
-	  any i/o. Thanks to Al Viro for advice on how to avoid the device i/o.
-	Thanks go to Andrew Morton for spotting the below:
-	- Fix buglet in allocate_compression_buffers() error code path.
-	- Call flush_dcache_page() after modifying page cache page contents in
-	  ntfs_file_readpage().
-	- Check for existence of page buffers throughout aops.c before calling
-	  create_empty_buffers(). This happens when an I/O error occurs and the
-	  read is retried. (It also happens once writing is implemented so that
-	  needed doing anyway but I had left it for later...)
-	- Don't BUG_ON() uptodate and/or mapped buffers throughout aops.c in
-	  readpage and read_block functions. Reasoning same as above (i.e. I/O
-	  error retries and future write code paths.)
-
-2.0.2 - Minor updates and cleanups.
-
-	- Cleanup: rename mst.c::__post_read_mst_fixup to post_write_mst_fixup
-	  and cleanup the code a bit, removing the unused size parameter.
-	- Change default fmask to 0177 and update documentation.
-	- Change attrib.c::get_attr_search_ctx() to return the search context
-	  directly instead of taking the address of a pointer. A return value
-	  of NULL means the allocation failed. Updated all callers
-	  appropriately.
-	- Update to 2.5.9 kernel (preserving backwards compatibility) by
-	  replacing all occurences of page->buffers with page_buffers(page).
-	- Fix minor bugs in runlist merging, also minor cleanup.
-	- Updates to bootsector layout and mft mirror contents descriptions.
-	- Small bug fix in error detection in unistr.c and some cleanups.
-	- Grow name buffer allocations in unistr.c in aligned mutlipled of 64
-	  bytes.
-
-2.0.1 - Minor updates.
-
-	- Make default umask correspond to documentation.
-	- Improve documentation.
-	- Set default mode to include execute bit. The {u,f,d}mask can be used
-	  to take it away if desired. This allows binaries to be executed from
-	  a mounted ntfs partition.
-
-2.0.0 - New version number. Remove TNG from the name. Now in the kernel.
-
-	- Add kill_super, just keeping up with the vfs changes in the kernel.
-	- Repeat some changes from tng-0.0.8 that somehow got lost on the way
-	  from the CVS import into BitKeeper.
-	- Begin to implement proper handling of allocated_size vs
-	  initialized_size vs data_size (i.e. i_size). Done are
-	  mft.c::ntfs_mft_readpage(), aops.c::end_buffer_read_index_async(),
-	  and attrib.c::load_attribute_list().
-	- Lock the runlist in attrib.c::load_attribute_list() while using it.
-	- Fix memory leak in ntfs_file_read_compressed_block() and generally
-	  clean up compress.c a little, removing some uncommented/unused debug
-	  code.
-	- Tidy up dir.c a little bit.
-	- Don't bother getting the runlist in inode.c::ntfs_read_inode().
-	- Merge mft.c::ntfs_mft_readpage() and aops.c::ntfs_index_readpage()
-	  creating aops.c::ntfs_mst_readpage(), improving the handling of
-	  holes and overflow in the process and implementing the correct
-	  equivalent of ntfs_file_get_block() in ntfs_mst_readpage() itself.
-	  I am aiming for correctness at the moment. Modularisation can come
-	  later.
-	- Rename aops.c::end_buffer_read_index_async() to
-	  end_buffer_read_mst_async() and optimize the overflow checking and
-	  handling.
-	- Use the host of the mftbmp address space mapping to hold the ntfs
-	  volume. This is needed so the async i/o completion handler can
-	  retrieve a pointer to the volume. Hopefully this will not cause
-	  problems elsewhere in the kernel... Otherwise will need to use a
-	  fake inode.
-	- Complete implementation of proper handling of allocated_size vs
-	  initialized_size vs data_size (i.e. i_size) in whole driver.
-	  Basically aops.c is now completely rewritten.
-	- Change NTFS driver name to just NTFS and set version number to 2.0.0
-	  to make a clear distinction from the old driver which is still on
-	  version 1.1.22.
-
-tng-0.0.8 - 08/03/2002 - Now using BitKeeper, http://linux-ntfs.bkbits.net/
-
-	- Replace bdevname(sb->s_dev) with sb->s_id.
-	- Remove now superfluous new-line characters in all callers of
-	  ntfs_debug().
-	- Apply kludge in ntfs_read_inode(), setting i_nlink to 1 for
-	  directories. Without this the "find" utility gets very upset which is
-	  fair enough as Linux/Unix do not support directory hard links.
-	- Further runlist merging work. (Richard Russon)
-	- Backwards compatibility for gcc-2.95. (Richard Russon)
-	- Update to kernel 2.5.5-pre1 and rediff the now tiny patch.
-	- Convert to new filesystem declaration using ->ntfs_get_sb() and
-	  replacing ntfs_read_super() with ntfs_fill_super().
-	- Set s_maxbytes to MAX_LFS_FILESIZE to avoid page cache page index
-	  overflow on 32-bit architectures.
-	- Cleanup upcase loading code to use ntfs_(un)map_page().
-	- Disable/reenable preemtion in critical sections of compession engine.
-	- Replace device size determination in ntfs_fill_super() with
-	  sb->s_bdev->bd_inode->i_size (in bytes) and remove now superfluous
-	  function super.c::get_nr_blocks().
-	- Implement a mount time option (show_inodes) allowing choice of which
-	  types of inode names readdir() returns and modify ntfs_filldir()
-	  accordingly. There are several parameters to show_inodes:
-		system:	system files
-		win32:	long file names (including POSIX file names) [DEFAULT]
-		long:	same as win32
-		dos:	short file names only (excluding POSIX file names)
-		short:	same as dos
-		posix:	same as both win32 and dos
-		all:	all file names
-	  Note that the options are additive, i.e. specifying:
-		-o show_inodes=system,show_inodes=win32,show_inodes=dos
-	  is the same as specifying:
-		-o show_inodes=all
-	  Note that the "posix" and "all" options will show all directory
-	  names, BUT the link count on each directory inode entry is set to 1,
-	  due to Linux not supporting directory hard links. This may well
-	  confuse some userspace applications, since the directory names will
-	  have the same inode numbers. Thus it is NOT advisable to use the
-	  "posix" or "all" options. We provide them only for completeness sake.
-	- Add copies of allocated_size, initialized_size, and compressed_size to
-	  the ntfs inode structure and set them up in
-	  inode.c::ntfs_read_inode(). These reflect the unnamed data attribute
-	  for files and the index allocation attribute for directories.
-	- Add copies of allocated_size and initialized_size to ntfs inode for
-	  $BITMAP attribute of large directories and set them up in
-	  inode.c::ntfs_read_inode().
-	- Add copies of allocated_size and initialized_size to ntfs volume for
-	  $BITMAP attribute of $MFT and set them up in
-	  super.c::load_system_files().
-	- Parse deprecated ntfs driver options (iocharset, show_sys_files,
-	  posix, and utf8) and tell user what the new options to use are. Note
-	  we still do support them but they will be removed with kernel 2.7.x.
-	- Change all occurences of integer long long printf formatting to hex
-	  as printk() will not support long long integer format if/when the
-	  div64 patch goes into the kernel.
-	- Make slab caches have stable names and change the names to what they
-	  were intended to be. These changes are required/made possible by the
-	  new slab cache name handling which removes the length limitation by
-	  requiring the caller of kmem_cache_create() to supply a stable name
-	  which is then referenced but not copied.
-	- Rename run_list structure to run_list_element and create a new
-	  run_list structure containing a pointer to a run_list_element
-	  structure and a read/write semaphore. Adapt all users of runlists
-	  to new scheme and take and release the lock as needed. This fixes a
-	  nasty race as the run_list changes even when inodes are locked for
-	  reading and even when the inode isn't locked at all, so we really
-	  needed the serialization. We use a semaphore rather than a spinlock
-	  as memory allocations can sleep and doing everything GFP_ATOMIC
-	  would be silly.
-	- Cleanup read_inode() removing all code checking for lowest_vcn != 0.
-	  This can never happen due to the nature of lookup_attr() and how we
-	  support attribute lists. If it did happen it would imply the inode
-	  being corrupt.
-	- Check for lowest_vcn != 0 in ntfs_read_inode() and mark the inode as
-	  bad if found.
-	- Update to 2.5.6-pre2 changes in struct address_space.
-	- Use parent_ino() when accessing d_parent inode number in dir.c.
-	- Import Sourceforge CVS repository into BitKeeper repository:
-		http://linux-ntfs.bkbits.net/ntfs-tng-2.5
-	- Update fs/Makefile, fs/Config.help, fs/Config.in, and
-	  Documentation/filesystems/ntfs.txt for NTFS TNG.
-	- Create kernel configuration option controlling whether debugging
-	  is enabled or not.
-	- Add the required export of end_buffer_io_sync() from the patches
-	  directory to the kernel code.
-	- Update inode.c::ntfs_show_options() with show_inodes mount option.
-	- Update errors mount option.
-
-tng-0.0.7 - 13/02/2002 - The driver is now feature complete for read-only!
-
-	- Cleanup mft.c and it's debug/error output in particular. Fix a minor
-	  bug in mapping of extent inodes. Update all the comments to fit all
-	  the recent code changes.
-	- Modify vcn_to_lcn() to cope with entirely unmapped runlists.
-	- Cleanups in compress.c, mostly comments and folding help.
-	- Implement attrib.c::map_run_list() as a generic helper.
-	- Make compress.c::ntfs_file_read_compressed_block() use map_run_list()
-	  thus making code shorter and enabling attribute list support.
-	- Cleanup incorrect use of [su]64 with %L printf format specifier in
-	  all source files. Type casts to [unsigned] long long added to correct
-	  the mismatches (important for architectures which have long long not
-	  being 64 bits).
-	- Merge async io completion handlers for directory indexes and $MFT
-	  data into one by setting the index_block_size{_bits} of the ntfs
-	  inode for $MFT to the mft_record_size{_bits} of the ntfs_volume.
-	- Cleanup aops.c, update comments.
-	- Make ntfs_file_get_block() use map_run_list() so all files now
-	  support attribute lists.
-	- Make ntfs_dir_readpage() almost verbatim copy of
-	  block_read_full_page() by using ntfs_file_get_block() with only real
-	  difference being the use of our own async io completion handler
-	  rather than the default one, thus reducing the amount of code and
-	  automatically enabling attribute list support for directory indices.
-	- Fix bug in load_attribute_list() - forgot to call brelse in error
-	  code path.
-	- Change parameters to find_attr() and lookup_attr(). We no longer
-	  pass in the upcase table and its length. These can be gotten from
-	  ctx->ntfs_ino->vol->upcase{_len}. Update all callers.
-	- Cleanups in attrib.c.
-	- Implement merging of runlists, attrib.c::merge_run_lists() and its
-	  helpers. (Richard Russon)
-	- Attribute lists part 2, attribute extents and multi part runlists:
-	  enable proper support for LCN_RL_NOT_MAPPED and automatic mapping of
-	  further runlist parts via attrib.c::map_run_list().
-	- Tiny endianness bug fix in decompress_mapping_pairs().
-
-tng-0.0.6 - Encrypted directories, bug fixes, cleanups, debugging enhancements.
-
-	- Enable encrypted directories. (Their index root is marked encrypted
-	  to indicate that new files in that directory should be created
-	  encrypted.)
-	- Fix bug in NInoBmpNonResident() macro. (Cut and paste error.)
-	- Enable $Extend system directory. Most (if not all) extended system
-	  files do not have unnamed data attributes so ntfs_read_inode() had to
-	  special case them but that is ok, as the special casing recovery
-	  happens inside an error code path so there is zero slow down in the
-	  normal fast path. The special casing is done by introducing a new
-	  function inode.c::ntfs_is_extended_system_file() which checks if any
-	  of the hard links in the inode point to $Extend as being their parent
-	  directory and if they do we assume this is an extended system file.
-	- Create a sysctl/proc interface to allow {dis,en}abling of debug output
-	  when compiled with -DDEBUG. Default is debug messages to be disabled.
-	  To enable them, one writes a non-zero value to /proc/sys/fs/ntfs-debug
-	  (if /proc is enabled) or uses sysctl(2) to effect the same (if sysctl
-	  interface is enabled). Inspired by old ntfs driver.
-	- Add debug_msgs insmod/kernel boot parameter to set whether debug
-	  messages are {dis,en}abled. This is useful to enable debug messages
-	  during ntfs initialization and is the only way to activate debugging
-	  when the sysctl interface is not enabled.
-	- Cleanup debug output in various places.
-	- Remove all dollar signs ($) from the source (except comments) to
-	  enable compilation on architectures whose gcc compiler does not
-	  support dollar signs in the names of variables/constants. Attribute
-	  types now start with AT_ instead of $ and $I30 is now just I30.
-	- Cleanup ntfs_lookup() and add consistency check of sequence numbers.
-	- Load complete runlist for $MFT/$BITMAP during mount and cleanup
-	  access functions. This means we now cope with $MFT/$BITMAP being
-	  spread accross several mft records.
-	- Disable modification of mft_zone_multiplier on remount. We can always
-	  reenable this later on if we really want to, but we will need to make
-	  sure we readjust the mft_zone size / layout accordingly.
-
-tng-0.0.5 - Modernize for 2.5.x and further in line-ing with Al Viro's comments.
-
-	- Use sb_set_blocksize() instead of set_blocksize() and verify the
-	  return value.
-	- Use sb_bread() instead of bread() throughout.
-	- Add index_vcn_size{_bits} to ntfs_inode structure to store the size
-	  of a directory index block vcn. Apply resulting simplifications in
-	  dir.c everywhere.
-	- Fix a small bug somewhere (but forgot what it was).
-	- Change ntfs_{debug,error,warning} to enable gcc to do type checking
-	  on the printf-format parameter list and fix bugs reported by gcc
-	  as a result. (Richard Russon)
-	- Move inode allocation strategy to Al's new stuff but maintain the
-	  divorce of ntfs_inode from struct inode. To achieve this we have two
-	  separate slab caches, one for big ntfs inodes containing a struct
-	  inode and pure ntfs inodes and at the same time fix some faulty
-	  error code paths in ntfs_read_inode().
-	- Show mount options in proc (inode.c::ntfs_show_options()).
-
-tng-0.0.4 - Big changes, getting in line with Al Viro's comments.
-
-	- Modified (un)map_mft_record functions to be common for read and write
-	  case. To specify which is which, added extra parameter at front of
-	  parameter list. Pass either READ or WRITE to this, each has the
-	  obvious meaning.
-	- General cleanups to allow for easier folding in vi.
-	- attrib.c::decompress_mapping_pairs() now accepts the old runlist
-	  argument, and invokes attrib.c::merge_run_lists() to merge the old
-	  and the new runlists.
-	- Removed attrib.c::find_first_attr().
-	- Implemented loading of attribute list and complete runlist for $MFT.
-	  This means we now cope with $MFT being spread across several mft
-	  records.
-	- Adapt to 2.5.2-pre9 and the changed create_empty_buffers() syntax.
-	- Adapt major/minor/kdev_t/[bk]devname stuff to new 2.5.x kernels.
-	- Make ntfs_volume be allocated via kmalloc() instead of using a slab
-	  cache. There are too little ntfs_volume structures at any one time
-	  to justify a private slab cache.
-	- Fix bogus kmap() use in async io completion. Now use kmap_atomic().
-	  Use KM_BIO_IRQ on advice from IRC/kernel...
-	- Use ntfs_map_page() in map_mft_record() and create ->readpage method
-	  for reading $MFT (ntfs_mft_readpage). In the process create dedicated
-	  address space operations (ntfs_mft_aops) for $MFT inode mapping. Also
-	  removed the now superfluous exports from the kernel core patch.
-	- Fix a bug where kfree() was used instead of ntfs_free().
-	- Change map_mft_record() to take ntfs_inode as argument instead of
-	  vfs inode. Dito for unmap_mft_record(). Adapt all callers.
-	- Add pointer to ntfs_volume to ntfs_inode.
-	- Add mft record number and sequence number to ntfs_inode. Stop using
-	  i_ino and i_generation for in-driver purposes.
-	- Implement attrib.c::merge_run_lists(). (Richard Russon)
-	- Remove use of proper inodes by extent inodes. Move i_ino and
-	  i_generation to ntfs_inode to do this. Apply simplifications that
-	  result and remove iget_no_wait(), etc.
-	- Pass ntfs_inode everywhere in the driver (used to be struct inode).
-	- Add reference counting in ntfs_inode for the ntfs inode itself and
-	  for the mapped mft record.
-	- Extend mft record mapping so we can (un)map extent mft records (new
-	  functions (un)map_extent_mft_record), and so mappings are reference
-	  counted and don't have to happen twice if already mapped - just ref
-	  count increases.
-	- Add -o iocharset as alias to -o nls for backwards compatibility.
-	- The latest core patch is now tiny. In fact just a single additional
-	  export is necessary over the base kernel.
-
-tng-0.0.3 - Cleanups, enhancements, bug fixes.
-
-	- Work on attrib.c::decompress_mapping_pairs() to detect base extents
-	  and setup the runlist appropriately using knowledge provided by the
-	  sizes in the base attribute record.
-	- Balance the get_/put_attr_search_ctx() calls so we don't leak memory
-	  any more.
-	- Introduce ntfs_malloc_nofs() and ntfs_free() to allocate/free a single
-	  page or use vmalloc depending on the amount of memory requested.
-	- Cleanup error output. The __FUNCTION__ "(): " is now added
-	  automatically. Introduced a new header file debug.h to support this
-	  and also moved ntfs_debug() function into it.
-	- Make reading of compressed files more intelligent and especially get
-	  rid of the vmalloc_nofs() from readpage(). This now uses per CPU
-	  buffers (allocated at first mount with cluster size <= 4kiB and
-	  deallocated on last umount with cluster size <= 4kiB), and
-	  asynchronous io for the compressed data using a list of buffer heads.
-	  Er, we use synchronous io as async io only works on whole pages
-	  covered by buffers and not on individual buffer heads...
-	- Bug fix for reading compressed files with sparse compression blocks.
-
-tng-0.0.2 - Now handles larger/fragmented/compressed volumes/files/dirs.
-
-	- Fixed handling of directories when cluster size exceeds index block
-	  size.
-	- Hide DOS only name space directory entries from readdir() but allow
-	  them in lookup(). This should fix the problem that Linux doesn't
-	  support directory hard links, while still allowing access to entries
-	  via their short file name. This also has the benefit of mimicking
-	  what Windows users are used to, so it is the ideal solution.
-	- Implemented sync_page everywhere so no more hangs in D state when
-	  waiting for a page.
-	- Stop using bforget() in favour of brelse().
-	- Stop locking buffers unnecessarily.
-	- Implemented compressed files (inode->mapping contains uncompressed
-	  data, raw compressed data is currently bread() into a vmalloc()ed
-	  memory buffer).
-	- Enable compressed directories. (Their index root is marked compressed
-	  to indicate that new files in that directory should be created
-	  compressed.)
-	- Use vsnprintf rather than vsprintf in the ntfs_error and ntfs_warning
-	  functions. (Thanks to Will Dyson for pointing this out.)
-	- Moved the ntfs_inode and ntfs_volume (the former ntfs_inode_info and
-	  ntfs_sb_info) out of the common inode and super_block structures and
-	  started using the generic_ip and generic_sbp pointers instead. This
-	  makes ntfs entirely private with respect to the kernel tree.
-	- Detect compiler version and abort with error message if gcc less than
-	  2.96 is used.
-	- Fix bug in name comparison function in unistr.c.
-	- Implement attribute lists part 1, the infrastructure: search contexts
-	  and operations, find_external_attr(), lookup_attr()) and make the
-	  code use the infrastructure.
-	- Fix stupid buffer overflow bug that became apparent on larger run
-	  list containing attributes.
-	- Fix bugs in readdir() that became apparent on larger directories.
-
-	The driver is now really useful and survives the test
-		find . -type f -exec md5sum "{}" \;
-	without any error messages on a over 1GiB sized partition with >16k
-	files on it, including compressed files and directories and many files
-	and directories with attribute lists.
-
-tng-0.0.1 - The first useful version.
-
-	- Added ntfs_lookup().
-	- Added default upcase generation and handling.
-	- Added compile options to be shown on module init.
-	- Many bug fixes that were "hidden" before.
-	- Update to latest kernel.
-	- Added ntfs_readdir().
-	- Added file operations for mmap(), read(), open() and llseek(). We just
-	  use the generic ones. The whole point of going through implementing
-	  readpage() methods and where possible get_block() call backs is that
-	  this allows us to make use of the generic high level methods provided
-	  by the kernel.
-
-	The driver is now actually useful! Yey. (-: It undoubtedly has got bugs
-	though and it doesn't implement accesssing compressed files yet. Also,
-	accessing files with attribute list attributes is not implemented yet
-	either. But for small or simple filesystems it should work and allow
-	you to list directories, use stat on directory entries and the file
-	system, open, read, mmap and llseek around in files. A big mile stone
-	has been reached!
-
-tng-0.0.0 - Initial version tag.
-
-	Initial driver implementation. The driver can mount and umount simple
-	NTFS filesystems (i.e. ones without attribute lists in the system
-	files). If the mount fails there might be problems in the error handling
-	code paths, so be warned. Otherwise it seems to be loading the system
-	files nicely and the mft record read mapping/unmapping seems to be
-	working nicely, too. Proof of inode metadata in the page cache and non-
-	resident file unnamed stream data in the page cache concepts is thus
-	complete.

+ * that dummy transactions are required to move the log into the idle state.
+ *
+ * Because this is called as part of the sync process, we should also indicate
+ * that dummy transactions should be issued in anything but the covered or
+ * idle states. This ensures that the log tail is accurately reflected in
+ * the log at the end of the sync, hence if a crash occurrs avoids replay

+ * For transmit packets, the header length must be a multiple of 4 and specifies
+ * the numbers of bytes in @header that will be prepended to the packet's
+ * payload; these bytes are copied into the kernel and will not be accessed
+ * after the ioctl has returned.  The sy and tag fields are copied to the iso
+ * packet header (these fields are specified by IEEE 1394a and IEC 61883-1).
+ * The skip flag specifies that no packet is to be sent in a frame; when using
+ * this, all other fields except the interrupt flag must be zero.
+ *
+ * For receive packets, the header length must be a multiple of the context's
+ * header size; if the header length is larger than the context's header size,
+ * multiple packets are queued for this entry.  The sy and tag fields are
+ * ignored.  If the sync flag is set, the context drops all packets until
+ * a packet with a matching sy field is received (the sync value to wait for is
+ * specified in the &fw_cdev_start_iso structure).  The payload length defines
+ * how many payload bytes can be received for one packet (in addition to payload
+ * quadlets that have been defined as headers and are stripped and returned in
+ * the &fw_cdev_event_iso_interrupt structure).  If more bytes are received, the
+ * additional bytes are dropped.  If less bytes are received, the remaining
+ * bytes in this part of the payload buffer will not be written to, not even by
+ * the next packet, i.e., packets received in consecutive frames will not
+ * necessarily be consecutive in memory.  If an entry has queued multiple
+ * packets, the payload length is divided equally among them.
+ *
+ * When a packet with the interrupt flag set has been completed, the
+ * &fw_cdev_event_iso_interrupt event will be sent.  An entry that has queued
+ * multiple receive packets is completed when its last packet is completed.

+perf-lock - Analyze lock events
+
+SYNOPSIS
+--------
+[verse]
+'perf lock' {record|report|trace}
+
+DESCRIPTION
+-----------
+You can analyze various lock behaviours
+and statistics with this 'perf lock' command.
+
+  'perf lock record <command>' records lock events
+  between start and end <command>. And this command
+  produces the file "perf.data" which contains tracing
+  results of lock events.
+
+  'perf lock trace' shows raw lock events.
+
+  'perf lock report' reports statistical data.
+
+SEE ALSO
