Hello.

Does not related to this patch, but...

the new lookup code first does a lightweight follow_page(), then if no page is present we do the get_user_pages() thing.
What if futex placed in VM_HUGETLB area?
Then follow_page() return garbage.

I think __pin_page(addr_in_hugetlb_area) has serious problems.

Oleg.
