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.
