Subject: [PATCH] ext2: Update also inode on disk when dir is IS_DIRSYNC

We used to just write changed page for IS_DIRSYNC inodes. But we also have to
update directory inode itself just for the case that we've allocated a new
block and changed i_size.

  Andrew, would you please merge the patch? Ext3 and ext4 don't have this
problem BTW.
