IIUC, memcg test includes intentional OOM-Kill test by setting the limit to 0.
And it has another test to set the limit to PAGE_SIZE.
In your environemnt, I think page size is 64kb...right ?
About rcu_sched_state()....I have no idea at this stage. I reviewed memcontrol.c
and oom_kill.c again and coundn't found anything in quick review.
Could you try again after -rc1 shipped ?
I think Andrew Morton sent some amount of updates for oom_kill and memcg, vmscan
to Linus, today.
Thanks,
