* driver-core: merge private parts of class and busKay Sievers2010-11-171-19/+19
| | | | | | | | | As classes and busses are pretty much the same thing, and we want to merge them together into a 'subsystem' in the future, let us share the same private data parts to make that merge easier.

* SYSFS: Allow boot time switching between deprecated and modern sysfs layoutAndi Kleen2010-10-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | I have some systems which need legacy sysfs due to old tools that are making assumptions that a directory can never be a symlink to another directory, and it's a big hazzle to compile separate kernels for them. This patch turns CONFIG_SYSFS_DEPRECATED into a run time option that can be switched on/off the kernel command line. This way the same binary can be used in both cases with just a option on the command line. The old CONFIG_SYSFS_DEPRECATED_V2 option is still there to set the default. I kept the weird name to not break existing config files. Also the compat code can be still completely disabled by undefining CONFIG_SYSFS_DEPRECATED_SWITCH -- just the optimizer takes care of this now instead of lots of ifdefs. This makes the code look nicer. v2: This is an updated version on top of Kay's patch to only handle the block devices. I tested it on my old systems and that seems to work.

* driver core: remove CONFIG_SYSFS_DEPRECATED_V2 but keep it for block devicesKay Sievers2010-10-221-19/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the old CONFIG_SYSFS_DEPRECATED_V2 config option, but it keeps the logic around to handle block devices in the old manner as some people like to run new kernel versions on old (pre 2007/2008) distros.

* Driver core: Constify struct sysfs_ops in struct kobj_typeEmese Revfy2010-03-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Constify struct sysfs_ops. This is part of the ops structure constification effort started by Arjan van de Ven et al. Benefits of this constification: * prevents modification of data that is shared (referenced) by many other structure instances at runtime * detects/prevents accidental (but not intentional) modification attempts on archs that enforce read-only kernel data at runtime * potentially better optimized code as the compiler can assume that the const data cannot be changed * the compiler/linker move const data into .rodata and therefore exclude them from false sharing Signed-off-by: Emese Revfy <re.emese@gmail.com> Acked-by: David Teigland <teigland@redhat.com> Acked-by: Matt Domsch <Matt_Domsch@dell.com> Acked-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Acked-by: Hans J.

* driver-core: Add attribute argument to class_attribute show/storeAndi Kleen2010-03-081-2/+2
| | | | | | | | | | | | | | | | | | | | Passing the attribute to the low level IO functions allows all kinds of cleanups, by sharing low level IO code without requiring an own function for every piece of data. Also drivers can extend the attributes with own data fields and use that in the low level function. This makes the class attributes the same as sysdev_class attributes and plain attributes. This will allow further cleanups in drivers. Full tree sweep converting all users. Signed-off-by: Andi Kleen <ak@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* Driver core: Add support for compatibility classesJean Delvare2009-09-151-0/+87
| | | | | | | | | | | | | | | | | | | | | When turning class devices into bus devices, we may need to temporarily add links in sysfs so that user-space applications are not confused. This is done by adding the following API: * Functions to register and unregister compatibility classes. These appear in sysfs at the same location as regular classes, but instead of class devices, they contain links to bus devices. * Functions to create and delete such links. Additionally, the caller can optionally pass a target device to which a "device" link should point (typically that would be the device's parent), to fully emulate the original class device. The i2c subsystem will be the first user of this API, as i2c adapters are being converted from class devices to bus devices.

* driver-core: use klist for class device list and implement iteratorTejun Heo2008-10-091-33/+103
| | | | | | | | | | | | | | | | | | | | | | Iterating over entries using callback usually isn't too fun especially when the entry being iterated over can't be manipulated freely. This patch converts class->p->class_devices to klist and implements class device iterator so that the users can freely build their own control structure. The users are also free to call back into class code without worrying about locking. class_for_each_device() and class_find_device() are converted to use the new iterators, so their users don't have to worry about locking anymore either. Note: This depends on klist-dont-iterate-over-deleted-entries patch because class_intf->add/remove_dev() depends on proper synchronization with device removal.

* sysfs: add /sys/dev/{char,block} to lookup sysfs path by major:minorDan Williams2008-07-221-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Why?: There are occasions where userspace would like to access sysfs attributes for a device but it may not know how sysfs has named the device or the path. For example what is the sysfs path for /dev/disk/by-id/ata-ST3160827AS_5MT004CK? With this change a call to stat(2) returns the major:minor then userspace can see that /sys/dev/block/8:32 links to /sys/block/sdc. What are the alternatives?: 1/ Add an ioctl to return the path: Doable, but sysfs is meant to reduce the need to proliferate ioctl interfaces into the kernel, so this seems counter productive. 2/ Use udev to create these symlinks: Also doable, but it adds a udev dependency to utilities that might be running in a limited environment like an initramfs. 3/ Do a full-tree search of sysfs.

* Driver core: change add_uevent_var to use a structKay Sievers2007-10-121-32/+10
| | | | | | | | | | | | | | | | | | This changes the uevent buffer functions to use a struct instead of a long list of parameters. It does no longer require the caller to do the proper buffer termination and size accounting, which is currently wrong in some places. It fixes a known bug where parts of the uevent environment are overwritten because of wrong index calculations. Many thanks to Mathieu Desnoyers for finding bugs and improving the error handling.

* driver-core: make devt_attr and uevent_attr staticTejun Heo2007-07-121-28/+16
| | | | | | | | | | | | | devt_attr and uevent_attr are either allocated dynamically with or embedded in device and class_device as they needed their owner field set to the module implementing the driver. Now that sysfs implements immediate disconnect and owner field removed from struct attribute, there is no reason to do this. Remove these attributes from [class_]device and use static attribute structures instead. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
