Subject: memcg: fix fatal livelock in kswapd
Date: Mon, 02 May 2011 15:07:29 -0500 [thread overview]
Message-ID: <1304366849.15370.27.camel@mulgrave.site> (raw)
The fatal livelock in kswapd, reported in this thread:
http://marc.info/?t=130392066000001
Is mitigateable if we prevent the cgroups code being so aggressive in
its zone shrinking (by reducing it's default shrink from 0 [everything]
to DEF_PRIORITY [some things]). This will have an obvious knock on
effect to cgroup accounting, but it's better than hanging systems.
