And the original request for discussion was more about user defined _policies_ for the global OOM rather than user space global OOM handler. I feel that there are usacases where the current "kill a single task based on some calculations" is far from optimal which leads to hacks which try to cope with after oom condition somehow gracefully. I do agree with you that pulling oom handling sounds too dangerous even with all the code that it would need and I feel we should go a different path than (ab)using memcg.oom_control interface for that. I still think we need to have a way to tell the global OOM killer what to do.
