This is overboard, to say the least, Could you be more specific about what is so "overboard" about this interface? I am not familiar with internals much, so I cannot judge the complexity part, but I thought that eventfd was intended for this kind of kernel->userspace notifications. > and I strongly think that cgroup should not any new usages of this > facility and preferably deprecate the existing usages if at all > possible. So you think that vmpressure, oom notification or thresholds are an abuse of this interface? What would you consider a reasonable replacement for those notifications? Or do you think that controller shouldn't be signaling any conditions to the userspace at all?
