Fix the race between capifs remount and node creation
Fix races around the access to ->s_options
switch ufs directories to ufs_sync_file()
Switch open_exec() and sys_uselib() to do_open_filp()
Make open_exec() and sys_uselib() use may_open(), instead of duplicating its parts
Reduce path_lookup() abuses
Make checkpatch.pl shut up on fs/inode.c
NULL noise in fs/super.c:kill_bdev_super()
romfs: cleanup romfs_fs.h
ROMFS: romfs_dev_read() error ignored
fs: dcache fix LRU ordering
ocfs2: Use nd_set_link().
Fix deadlock in ipathfs ->get_sb()
Fix a leak in failure exit in 9p ->get_sb()
Convert obvious places to deactivate_locked_super()
New helper: deactivate_locked_super()
reiserfs: remove privroot hiding in lookup
reiserfs: dont associate security.* with xattr files
