Subject[PATCH v3 0/2] support multi-size THP numa balancing
Date
This patchset tries to support mTHP numa balancing, as a simple solution
to start, the NUMA balancing algorithm for mTHP will follow the THP strategy
as the basic support. Please find details in each patch.

Changes from v2:
- Add reviewed tag from Huang, Ying.
- Reuse numa_rebuild_single_mapping() to remove duplicate code per Kefeng Wang.
- Remove an unnecessary vma_wants_manual_pte_write_upgrad() per Huang, Ying.

Changes from v1:
- Fix the issue where the end address might exceed the range of the
folio size, suggested by Huang, Ying.
- Simplify the folio validation.
- Add pte_modify() before checking pte writable.
- Update the performance data.

Changes from RFC v2:
- Follow the THP algorithm per Huang, Ying.

Changes from RFC v1:
- Add some preformance data per Huang, Ying.
- Allow mTHP scanning per David Hildenbrand.
- Avoid sharing mapping for numa balancing to avoid false sharing.
- Add more commit message.

Baolin Wang (2):
mm: factor out the numa mapping rebuilding into a new helper
mm: support multi-size THP numa balancing
