Subject: ext2: also update the inode on disk when dir is IS_DIRSYNC
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=6b7021ef7e1a703c7092daeceda063951b22b4f6;p=deliverable%2Flinux.git

ext2: also update the 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 the directory inode itself just for the case that we've
allocated a new block and changed i_size.
