Subject: [PATCH 0/2] Use up free swap space before reaching OOM kill
Date: Wed, 9 Jan 2013 15:21:12 +0900 [thread overview]
Message-ID: <1357712474-27595-1-git-send-email-minchan@kernel.org> (raw)
Recently, Luigi reported there are lots of free swap space when
OOM happens. It's easily reproduced on zram-over-swap, where
many instance of memory hogs are running and laptop_mode = 2.
http://marc.info/?l=linux-mm&m=135421750914807&w=2
This patchset fixes the problem. In fact, if we apply one of two,
we can fix the problem but I send two all because it's separate
issue although each of them solves this issues.
Andrew, Could you replace [1] with this patchset in mmotm?
I think this patchset is better than [1].
[1] mm-swap-out-anonymous-page-regardless-of-laptop_mode.patch
Minchan Kim (2):
[1/2] mm: prevent to add a page to swap if may_writepage is unset
[2/2] mm: forcely swapout when we are out of page cache
