The main reason for sending out this patch is to figure out what exactly is in your mind before enabling cpuset in v2. >From my point of view, the exclusive setting makes cpuset behave more like a resource domain that a resource allocated to one cgroup won't be available for another cgroup. So we can argue it both ways whether it violates the basic hierarchy rules or not. I will be in the Plumbers Conference next month and we can talk more about this. My goal is to make cgroup v2 ready for prime time hopefully by the end of the year.
