Yes. it doesn't change many subtle things and make much fair but the
Wu's concern is order-0 pages with __GFP_NORETRY. By his experiment,
my patch doesn't help much his concern.
The problem I have is I don't have any infrastructure for reproducing
his experiment. :(

I want it but the day would be after finishing inorder-putback series. :)
Maybe you have a environment(8core system). If you want it, go ahead. :)

Thanks, KOSAKI.
