Subject: [PATCH v4 0/8] extend hugepage migration
Here is the 4th version of hugepage migration patchset.
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?
Thanks,
Naoya Horiguchi
