Subject: [patch 00/11 -mm v4] oom killer rewrite
Date: Wed, 17 Mar 2010 01:55:19 -0700 (PDT) [thread overview]
Message-ID: <alpine.DEB.2.00.1003170151540.31796@chino.kir.corp.google.com> (raw)
This patchset is a rewrite of the out of memory killer to address several
issues that have been raised recently. The most notable change is a
complete rewrite of the badness heuristic that determines which task is
killed; the goal was to make it as simple and predictable as possible
while still addressing issues that plague the VM.
Changes for version 4:
- updated to mmotm-2010-03-11-13-13
- rewrote mem_cgroup_get_limit() to respect swapless systems or those
where users have not configured a swap limit (suggested by KAMEZAWA
Hiroyuki).
- added: [patch 11/11] oom: avoid race for oom killed tasks detaching mm
prior to exit
To apply, download the -mm tree from
http://userweb.kernel.org/~akpm/mmotm/broken-out.tar.gz first.
This patchset is also available for each kernel release from:
http://www.kernel.org/pub/linux/kernel/people/rientjes/oom-killer-rewrite/
including broken out patches.
