In your patch, oom_kill in memory.oom_control specifies that number of oom events that resulted in an oom kill of a process from that hierarchy, but not the number of processes killed from a specific memcg (the difference between oc->memcg and mem_cgroup_from_task(victim)). Not sure if you would also find it helpful. -- To unsubscribe from this list: send the line "unsubscribe cgroups" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
