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
