[PATCH] ext2: update inode ctime on rename()

The ext2fs filesystem on 2.2 and 2.6, as well as other filesystems
on 2.4 update the inode ctime on rename(). When this fix was applied
to 2.2.13, it was applied to the ext3 tree at the same time, but the
ext2 tree was forgotten. It was recently fixed in 2.6, but 2.4 was
forgotten again. Here's the fix.

First reported by Chris Siebenmann on 10 Jan 2004 !
