Thank you for letting me know. Note that before this patch I saw the one from Sameer Nanda mm, oom: Fix race when selecting process to kill https://lkml.org/lkml/2013/11/13/336 After applying this later one, I still have the issue I sent you (oom killing a task outside cgroup i.e Task in / killed as a result of limit of /lxc/foo) *but* I don't have a crash any more. So I was in the process of reapplying your debug patch to send you a new report. However, I'm now wondering if this present patch is a replacement of Sameer Nanda's patch or if this a complementary patch.
