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. https://www.spinics.net/lists/linux-mm/msg153212.html https://lore.kernel.org/lkml/201807130620.w6D6KiAJ093010@www262.sakura.ne.jp/T/#u On 2018/07/14 10:55, Tetsuo Handa wrote: > On 2018/07/14 6:59, David Rientjes wrote: >> I'm not trying to preclude the cgroup-aware oom killer from being merged, >> I'm the only person actively trying to get it merged. > > Before merging the cgroup-aware oom killer, can we merge OOM lockup fixes > and my cleanup?
