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

From: Marcelo Tosatti <marcelo.tosatti@cyclades.com>

Chris Siebenmann posted a fix to update the old inode ctime on rename().

This fix went into 2.2.13, but did not make into 2.4 or 2.6 kernels (the
2.2.13 diff is at the end of this message).

Here is updated 2.6 version without mark_inode_dirty(), which is not
necessary anymore because its called by "ext2_dec_count()" few lines down.
