Yes, and thank you very much for working on v8 to remove the dependency on 
page_cgroup and to seperate this out.  I think it will benefit users who 
don't want to enable all of memcg but still want to account and restrict 
hugetlb page usage, and I think the code seperation is much cleaner 
internally.

I'll review that patchset and suggest that the old hugetlb extension in 
-mm be dropped in the interim.
