I added Reviewed/Acked tags and applied the feedbacks in the previous discussion (thank you, all reviewers!): - fixed macro (1/8) - improved comment and readability (1/8, 3/8, 4/8, 7/8) - improved node choice in allocating destination hugepage (7/8) TODOs: (likely to be done after this work) - split page table lock for pmd/pud based hugepage (maybe applicable to thp) - improve alloc_migrate_target (especially in node choice) - using page walker in check_range I hope that this series is becoming ready to be merge to -mm tree. Andrew, could you review and judge this?
