I read that as there is a fundamental problem to update existing binaries. If that is the case then there surely is no way around it and another sad page in the screwed up APIs book we provide. But I was under impression that the SW stack which actually does the monitoring is under your controll. Moreover I was under impression that you do not use the current vanilla kernel so there is no need for an immediate change on your end. It is trivial to come up with a backward compatible way to check for the new flag (if it is not present then fallback to vma flags). I am sorry for pushing here but if this is just a matter of a _single_ user which _can_ be fixed with a reasonable effort then I would love to see the future api unscrewed. -- Michal Hocko SUSE Labs
