I do not think we have discussed anything resembling the current approach. And I would really appreciate some more examples where decisions based on leaf nodes would be EXACTLY WRONG. > We need OOM behavior to kill in a deterministic order configured by > policy. And nobody is objecting to this usecase. I think we can build a priority policy on top of leaf-based decision as well. The main point we are trying to sort out here is a reasonable semantic that would work for most workloads. Sibling based selection will simply not work on those that have to use deeper hierarchies for organizational purposes. I haven't heard a counter argument for that example yet. -- Michal Hocko SUSE Labs -- 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
