Subject: [patch 00/18] oom killer rewrite
Date: Sun, 6 Jun 2010 15:33:53 -0700 (PDT)	[thread overview]
Message-ID: <alpine.DEB.2.00.1006061520520.32225@chino.kir.corp.google.com> (raw)

This is the latest update of the oom killer rewrite based on
mmotm-2010-06-03-16-36, although it applies cleanly to 2.6.35-rc2 as
well.

There are two changes in this update, which I hope to now be considered
for -mm inclusion and pushed for 2.6.36:

 - reordered the patches to more accurately seperate fixes from
   enhancements: the order is now very close to how KAMEZAWA Hiroyuki
   suggested (thanks!), and

 - the changelog for "oom: badness heuristic rewrite" was slightly
   expanded to mention how this rewrite improves the oom killer's
   behavior on the desktop.

Many thanks to Nick Piggin <npiggin@suse.de> for converting the remaining
architectures that weren't using the oom killer to handle pagefault oom
conditions to do so.  His patches have hit mainline, so there is no
longer an inconsistency in the semantics of panic_on_oom in such cases!

Many thanks to KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> for his
help and patience in working with me on this patchset.
