[GIT PATCH] driver core patches for 2.6.33-git

[GIT PATCH] driver core patches for 2.6.33-git

[Greg KH]

Here is the big driver core merge for the 2.6.33-git tree.

Nothing major here:
	- sysfs reworks to make things nicer and fix minor problems
	- firmware api changes
	- devtmpfs tweaks to resolve minor issues reported by users.
	- platform devices early buffer changes
	- debugfs bugfix

Please pull from:
	master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-core-2.6.git/

All of these patches have been in the linux-next and mm trees for a
while.

The patches will be sent as a follow-on to this message to lkml for people
to see.

thanks,

greg k-h

[PATCH 09/27] firmware_class: make request_firmware_nowait more useful

[Greg Kroah-Hartman]

From: Johannes Berg <johannes@sipsolutions.net>

Unfortunately, one cannot hold on to the struct firmware
that request_firmware_nowait() hands off, which is needed
in some cases. Allow this by requiring the callback to
free it (via release_firmware).

Additionally, give it a gfp_t parameter -- all the current
users call it from a GFP_KERNEL context so the GFP_ATOMIC
isn't necessary. This also marks an API break which is
useful in a sense, although that is obviously not the
primary purpose of this change.

[PATCH 10/27] Driver core: Don't remove kobjects in device_shutdown.

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@xmission.com>

device_shutdown is defined to just shutdown the hardware and to not
clean up any kernel data structures.  Therefore don't put the kobjects
for /sys/dev and /sys/dev/block and /sys/dev/char.

This ensures we don't remove /sys/dev/block and /sys/dev/char while
we still have symlinks from there to the actual devices.

[PATCH 11/27] debugfs: fix create mutex racy fops and private data

[Greg Kroah-Hartman]

From: Mathieu Desnoyers <mathieu.desnoyers@polymtl.ca>

Setting fops and private data outside of the mutex at debugfs file
creation introduces a race where the files can be opened with the wrong
file operations and private data.  It is easy to trigger with a process
waiting on file creation notification.

Using dentry instead of d in the function name is what
several other filesystems are doing and it seems to be
a more readable convention.

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@xmission.com>

Calling d_drop unconditionally when a sysfs_dirent is deleted has
the potential to leak mounts, so instead implement dentry delete
and revalidate operations that cause sysfs dentries to be removed
at the appropriate time.

[PATCH 15/27] sysfs: Simplify sysfs_chmod_file semantics

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@xmission.com>

Currently every caller of sysfs_chmod_file happens at either
file creation time to set a non-default mode or in response
to a specific user requested space change in policy.  Making
timestamps of when the chmod happens and notification of
a file changing mode uninteresting.

Remove the unnecessary time stamp and filesystem change
notification, and removes the last of the explicit inotify
and donitfy support from sysfs.

[PATCH 16/27] sysfs: Simplify iattr time assignments

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@xmission.com>

The granularity of sysfs time when we keep it is 1 ns.  Which
when passed to timestamp_trunc results in a nop.  So remove
the unnecessary function call making sysfs_setattr slightly
easier to read.

[PATCH 20/27] sysfs: Implement sysfs_getattr & sysfs_permission

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@xmission.com>

With the implementation of sysfs_getattr and sysfs_permission
sysfs becomes able to lazily propogate inode attribute changes
from the sysfs_dirents to the vfs inodes.   This paves the way
for deleting significant chunks of now unnecessary code.

While doing this we did not reference sysfs_setattr from
sysfs_symlink_inode_operations so I added along with
sysfs_getattr and sysfs_permission.

[PATCH 22/27] sysfs: Gut sysfs_addrm_start and sysfs_addrm_finish

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@maxwell.aristanetworks.com>

With lazy inode updates and dentry operations bringing everything
into sync on demand there is no longer any need to immediately
update the vfs or grab i_mutex to protect those updates as we
make changes to sysfs.

[PATCH 23/27] sysfs: Propagate renames to the vfs on demand

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@xmission.com>

By teaching sysfs_revalidate to hide a dentry for
a sysfs_dirent if the sysfs_dirent has been renamed,
and by teaching sysfs_lookup to return the original
dentry if the sysfs dirent has been renamed.  I can
show the results of renames correctly without having to
update the dcache during the directory rename.

This massively simplifies the rename logic allowing a lot
of weird sysfs special cases to be removed along with
a lot of now unnecesary helper code.

[PATCH 24/27] sysfs: Factor out sysfs_rename from sysfs_rename_dir and sysfs_move_dir

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@xmission.com>

These two functions do 90% of the same work and it doesn't significantly
obfuscate the function to allow both the parent dir and the name to change
at the same time.  So merge them together to simplify maintenance, and
increase testing.

[PATCH 25/27] sysfs: sysfs_setattr remove unnecessary permission check.

[Greg Kroah-Hartman]

From: Eric W. Biederman <ebiederm@maxwell.aristanetworks.com>

inode_change_ok already clears the SGID bit when necessary
so there is no reason for sysfs_setattr to carry code to do
the same, and it is good to kill the extra copy because when
I moved the code last in certain corner cases the code will
look at the wrong gid.

[PATCH 26/27] Driver Core: Early platform driver buffer

[Greg Kroah-Hartman]

From: Magnus Damm <damm@opensource.se>

Add early_platform_init_buffer() support and update the
early platform driver code to allow passing parameters
to the driver on the kernel command line.

early_platform_init_buffer() simply allows early platform
drivers to provide a pointer and length to a memory area
where the remaining part of the kernel command line option
will be stored.

Needed to pass baud rate and other serial port options
to the reworked early serial console code on SuperH.

[PATCH 27/27] Driver core: fix race in dev_driver_string

[Greg Kroah-Hartman]

From: Alan Stern <stern@rowland.harvard.edu>

This patch (as1310) works around a race in dev_driver_string().  If
the device is unbound while the function is running, dev->driver might
become NULL after we test it and before we dereference it.

One more problem: you don't unlock dirlock if kstrdup() failed.

[GIT PATCH] driver core patches for 2.6.33-git

[Greg KH]

Here are some 2.6.33-rc1 patches for the driver core:

Nothing major here:
	- fixes for devtmpfs warnings on lockdep and command line
	  options
	- documentation updates
	- api change to make attributes const.  This is added now so
	  that subsystem maintainers can queue up patches for .34.  This
	  was submitted now at the recommendation of Stephen Rothwell.
	- stable kernel rules clarification in the documentation

Please pull from:
	master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-core-2.6.git/

All of these patches have been in the linux-next and mm trees.

The patches will be sent as a follow-on to this message to lkml for people
to see.

thanks,

greg k-h

I've now updated this series, fixing the 'default y' option for the
DEVTMPFS config options, and respun it on top of your tree as of a few
days ago.

Please pull from:
	master.kernel.org:/pub/scm/linux/kernel/git/gregkh/driver-core-2.6.git/

The updated diffstat and shortlog is below.
