+From: Jan Kara <jack@suse.cz>
+Subject: [PATCH] ext2: Do not update mtime of a move directory when parent has not changed
+References: bnc#493392
+Patch-mainline: 2.6.30
+
+If the parent of the moved directory has not changed, there's no real
+reason to change mtime. Specs doesn't seem to say anything about this
+particular case and e.g. ext3 does not change mtime in this case.
+So we become a tiny bit more consistent.
+
+Spotted by ronny.pretzsch@dfs.de, initial fix by Jörn Engel <joern@logfs.org>.
