Nit: the subject is still somewhat misleading IMHO, especially in light
of Mike's responses. I would say "reclaim as needed" instead of
"excessively reclaim". The excessive reclaim behavior in hugetlb nr_pages
setting was a bug that was addressed by a different series.

I still believe that using __GFP_NORETRY as needed is a cleaner solution
than a check for pageblock order and __GFP_IO, but that can be always
changed later. This patch does fix the hugetlbfs regression, so
