Subject: [PATCH][mmotm-2010-02-01-16-25] Fix wrong accouting of anon and
 file

Unfortunately, Kame said he doesn't support this series.
I am not sure we need this patch or revert patch.

Who need this?

David. Do you want to remain this patch in mmotm for your OOM patch 
in future?

If anyone doesn't reply my question, Do we have to make revert patch?

== CUT_HERE == 

mm-count-lowmem-rss.patch added lowmem accouting.
But it changed file and rss accouting by mistake.
Unfortunately my review also doesn't found it.

This patch fixes it.
