I'm on CC this time :-) Unfortunately I have a planned holiday starting tomorrow, so won't get a chance to do proper review till I'm back which would be few weeks from now. I just want to iterate that this is a real problem being seen in practice where it's hard to provide a single average EM for all workloads now. So we certainly need something like this. Hopefully I'll get a chance to help with review when I'm back from holidays. Thanks! -- Qais Yousef

I am going to address comments from Rafael. So probably when you're back the v5 would be there then. Regards, Lukasz
