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
