Understood.  I haven't looked at the code, so my opinion was based on
the assumption that the whole thing is completely separate (in design
and implementation) from memcg as hugtlbfs is from the usual mm.  If
it's better / easier implemented together with memcg, I have no
objection to making it part of memcg.

Thanks.
