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.
