We want to handle global OOM in a more user defined ways but we have to agree on the proper interface first. I do not want to end up with something half baked with memcg and a different interface to do the real thing just because memcg turns out to be unsuitable. And to be honest, the more I am thinking about memcg based interface the stronger is my feeling that it is unsuitable for the user defined OOM policies. But that should be discussed properly (I will send a RFD in the follow up days).
