Subject: [PATCH 0/6] page cgroup diet v5
Date: Fri, 17 Feb 2012 18:24:26 +0900 [thread overview]
Message-ID: <20120217182426.86aebfde.kamezawa.hiroyu@jp.fujitsu.com> (raw)
This patch set is for removing 2 flags PCG_FILE_MAPPED and PCG_MOVE_LOCK on
page_cgroup->flags. After this, page_cgroup has only 3bits of flags.
And, this set introduces a new method to update page status accounting per memcg.
With it, we don't have to add new flags onto page_cgroup if 'struct page' has
information. This will be good for avoiding a new flag for page_cgroup.
Fixed pointed out parts.
- added more comments
- fixed texts
- removed redundant arguments.
Passed some tests on 3.3.0-rc3-next-20120216.
Thanks,
-Kame
