* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs-2.6: (87 commits) nilfs2: get rid of bd_mount_sem use from nilfs nilfs2: correct exclusion control in nilfs_remount function nilfs2: simplify remaining sget() use nilfs2: get rid of sget use for checking if current mount is present nilfs2: get rid of sget use for acquiring nilfs object nilfs2: remove meaningless EBUSY case from nilfs_get_sb function remove the call to ->write_super in __sync_filesystem nilfs2: call nilfs2_write_super from nilfs2_sync_fs jffs2: call jffs2_write_super from jffs2_sync_fs ufs: add ->sync_fs sysv: add ->sync_fs hfsplus: add ->sync_fs hfs: add ->sync_fs fat: add ->sync_fs ext2: add ->sync_fs exofs: add ->sync_fs bfs: add ->sync_fs affs: add ->sync_fs sanitize ->fsync() for affs repair bfs_write_inode(), switch bfs to simple_fsync() ...
