Heh, that's helping me a lot and makes get_one_user_page very simple again (and simplify the follow_huge_* stuff even more). This could help futex slow-path and remove loads of code. Once this hugetlb stuff settles down a bit, I'll rewrite the page-walking again to accomodate this. No API changes, just internal rewrites. So please tell the linux-mm list, when it's finished and I'll have sth. ready for -mm in the first week of March[1].
