I haven't started looking at this series yet. However, since Mina was involved in the discussion of that patch (hugetlb controller for cgroups v2) my assumption is that this patch would simply build on that v2 support? Seems like the above patch would be a prereq for this series. Mina, are those assumptions correct and perhaps this is an old/obsolete comment? Does this series apply 'on top' of the above patch? That patch is already in Andrew's tree. -- Mike Kravetz
