Do I apply the 3 > patches on top of my patchset or they comes separately? Ah, sorry, I made patches on mmotm-Apr15 + Your Patch 1-8. (not including 9,10) I dropped 10 just because of HUNK (caused by dropping 9) but as David pointed out, we should make a consolidation with count_vm_event() (in different patch set)... And I think you already have v7. For this time, you can pick usable parts up to your set. I'll make an add-on again. What imporatant here will be discussion for better implemenation.
