Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6:
get rid of BKL in fs/sysv
get rid of BKL in fs/minix
get rid of BKL in fs/efs
befs ->pust_super() doesn't need BKL
Cleanup of adfs headers
9P doesn't need BKL in ->umount_begin()
fuse doesn't need BKL in ->umount_begin()
No instance of ->bmap() needs BKL
remove unlock_kernel() left accidentally
ext4: avoid unnecessary spinlock in critical POSIX ACL path
ext3: avoid unnecessary spinlock in critical POSIX ACL path
