For patches 1-5 and 8: Acked-by: Andrea Arcangeli <aarcange@xxxxxxxxxx> Patch 6-7 I've to trust this branch is really worth it, I agree khugepaged can hardly be better, but this comes at the cost of one more branch for something that looks minor issue. I'm netural if others likes it it's sure fine with me (I think David didn't like it though, but he didn't answer to last email from Andi, I'm CCing him in case he wants to elaborate further). My patch incremental with patch 8 is also needed. My patch incremental with patch 7 is also needed if 6-7 gets applied. They're good to be in 2.6.38 but I don't rate them extremely urgent with the exception of patch 1 that is already in -mm in fact. In some ways this also shows how the default numa policy is inefficient if the best it can do is to look at where the page was allocated initially without any knowledge of where the task run last but I don't want to risk making things worse, so for the short term it's ok fix (it's not a band-aid it's really a fix for an heuristic that is not good enough and it can't make things worse unlike the KSM change in previous series that definitely made things worse), but I hope in the long term getting info from the page in khugepaged won't be needed anymore and it can be rolled back.
