Fix kernel-doc errors and warnings in new header file kfifo.h. Don't use kernel-doc "/**" for internal functions whose comments are not in kernel-doc format. kernel-doc section header names (like "Note:") must be unique per function. Looks like I need to document that. Error(include/linux/kfifo.h:76): duplicate section name 'Note' Warning(include/linux/kfifo.h:88): Excess function parameter 'size' description in 'INIT_KFIFO' Error(include/linux/kfifo.h:101): duplicate section name 'Note' Warning(include/linux/kfifo.h:257): No description found for parameter 'fifo' (many of this last type, from internal functions) Signed-off-by:Randy Dunlap <randy.dunlap@oracle.com> Cc: Stefani Seibold <stefani@seibold.net> Signed-off-by:

The USB serial code was a new user of the kfifo API, and it was missed when porting things to the new kfifo API. Please make the write_fifo in place. Here is my patch to fix the regression and full ported version. Signed-off-by:

Eric Sandeen authored
The function ext3_mark_recovery_complete() is called from two call paths: either (a) while mounting the filesystem, in which case there's no danger of any other CPU calling write_super() until the mount is completed, and (b) while remounting the filesystem read-write, in which case the fs core has already locked the superblock. This also allows us to take out a very vile unlock_super()/lock_super() pair in ext3_remount(). Port of ext4 commit a63c9eb2 by Theodore Ts'o <tytso@mit.edu>.

Currently inode_reservation is managed by fs itself and this reservation is transfered on dquot_transfer(). This means what inode_reservation must always be in sync with dquot->dq_dqb.dqb_rsvspace. Otherwise dquot_transfer() will result in incorrect quota(WARN_ON in dquot_claim_reserved_space() will be triggered) This is not easy because of complex locking order issues for example http://bugzilla.kernel.org/show_bug.cgi?id=14739 The patch introduce quota reservation field for each fs-inode (fs specific inode is used in order to prevent bloating generic vfs inode). This reservation is managed by quota code internally similar to i_blocks/i_bytes and may not be always in sync with internal fs reservation. Also perform some code rearrangement: - Unify dquot_reserve_space() and dquot_reserve_space() - Unify dquot_release_reserved_space() and dquot_free_space() - Also this patch add missing warning update to release_rsv() dquot_release_reserved_space() must call flush_warnings() as dquot_free_space() does.

Effectively reverts 738d2be4. As demonstrated by Eric, we really need to call __set_task_cpu() early in the fork() path to properly initialize the various task state -- specifically the cgroup state through set_task_rq(). [ we could probably fix this by explicitly calling __set_task_cpu() from sched_fork(), but lets try that for the next cycle and simply revert to the old behaviour for now. ] Reported-by:

This fixes LVDS on some mac laptops without a panel edid. v2 - Set proper mode type flags v3 - Note that this is not neceesarily the exact panel mode, but an approximation based on the cvt formula. For these systems we should ideally read the mode info out of the registers or add a mode table, but this works and is much simpler. v4 - Update comments and debug message. Signed-off-by:
