Subject: [patch 00/10 -mm v3] oom killer rewrite
Date: Wed, 10 Mar 2010 02:41:08 -0800 (PST) [thread overview]
Message-ID: <alpine.DEB.2.00.1003100236510.30013@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 from version 2:
- updated to mmotm-2010-03-09-19-15
- schedule a timeout for current if it was not selected for oom kill
when it has returned VM_FAULT_OOM so memory can freed to prevent
needlessly recalling the oom killer and looping.
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.
