Subject: [PATCH V2 0/2] Provide more precise dump info for memcg-oom
Date: Wed, 7 Nov 2012 16:40:02 +0800 [thread overview]
Message-ID: <1352277602-21687-1-git-send-email-handai.szj@taobao.com> (raw)
From: Sha Zhengju <handai.szj@taobao.com>
When memcg oom is happening the current memcg related dump information
is limited for debugging. The patches provide more detailed memcg page statistics
and also take hierarchy into consideration.
The previous primitive version can be reached here: https://lkml.org/lkml/2012/7/30/179.
Change log:
1. some modification towards hierarchy
2. rework dump_tasks
3. rebased on Michal's mm tree since-3.6
Any comments are welcomed. : )
