Subject: Some questions about cgroup aware OOM killer.

From: yuzhoujian <yuzhoujian@...ichuxing.com>

Hi Roman
I've read your patchset about cgroup aware OOM killer, and try
to merge your patchset to the upstream kernel(v4.17-rc1). But
I found some functions which in your patch([PATCH v13 3/7] 
mm, oom: cgroup-aware OOM killer) does not exist in the upstream
kernel. Which version of the kernel do you patch on? And, do you
have the latest patchset?

The faults in PATCH v13 3/7:
1. mm/oom_kill.o: In function `out_of_memory':
   /linux/mm/oom_kill.c:1125: undefined reference to `alloc_pages_before_oomkill'
2. mm/oom_kill.c: In function ‘out_of_memory’:
   mm/oom_kill.c:1125:5: error: ‘struct oom_control’ has no member named ‘page’
   oc->page = alloc_pages_before_oomkill(oc);
     ^

Best wishes
