Do you see my old patch? The patch want't incomplet but it's not bad for showing an idea.^^^^^^^^^^^^^^^^ typo : wasn't completeI think your idea is eligible. Wu's approach may increase throughput but
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. :(
may decrease latency. So, do you have a plan to finish the work?

If you want it, go ahead. :) Thanks, KOSAKI. -- Kind regards, Minchan Kim -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
