From: Li Zefan Subject: [PATCH 0/8] memcg, cgroup: kill css_id Date: Mon, 8 Apr 2013 16:19:53 +0800 Message-ID: <51627DA9.7020507@huawei.com> Mime-Version: 1.0 Content-Transfer-Encoding: 7bit Return-path: Sender: cgroups-owner-u79uwXL29TY76Z2rM5mHXA@public.gmane.org List-ID: Content-Type: text/plain; charset="us-ascii" To: Andrew Morton Cc: Tejun Heo , Glauber Costa , KAMEZAWA Hiroyuki , Michal Hocko , Johannes Weiner , LKML , Cgroups , linux-mm-Bw31MaZKKs3YtjvyW6yDsg@public.gmane.org (This patchset depends on "memcg: make memcg's life cycle the same as cgroup") This patchset converts memcg to always use cgroup->id, and then kills css_id. As we've removed memcg's own refcnt, converting memcg to use cgroup->id is very straight-forward.
