Minor matter: that's non-responsive to my suggestion.

If it's moved to a new cgroup then we can just go back to the original 
point that I made as was trying to avoid: adding #ifdefs all over 
mm/memcontrol.c in a dozen or so places.  A mm/hugetlbcg.c would only be 
built, natually, when we have "depends on HUGETLB_PAGE" and 
linux/hugetlb.h takes care of the rest (setting HUGE_MAX_HSTATE for archs 
that don't define it themselves, in other words only one hugepage size).

And if it isn't moved to a new cgroup then your
memcg-add-hugetlb-extension-fix.patch is suboptimal.  Why is this so
hard?
