[PATCH] reiserfs: use mark_inode_dirty instead of reiserfs_update_sd
reiserfs should use mark_inode_dirty during reiserfs_file_write and reiserfs_commit_write. This makes sure the inode is properly flagged as dirty, which is used during O_SYNC to decide when to trigger log commits. This patch also removes the O_SYNC check from reiserfs_commit_write, since that gets dealt with properly at higher layers once we start using mark_inode_dirty. Thanks to Hifumi Hisashi <hifumi.hisashi@lab.ntt.co.jp> for catching this. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
