Subject: Re: [PATCH v13 0/7] cgroup-aware OOM killer

No response from Roman and David...

Andrew, will you once drop Roman's cgroup-aware OOM killer and David's patches?
Roman's series has a bug which I mentioned and which can be avoided by my patch.
David's patch is using MMF_UNSTABLE incorrectly such that it might start selecting
next OOM victim without trying to reclaim any memory.

Since they are not responding to my mail, I suggest once dropping from linux-next.
