Earlier versions were posted previously [1] and [2]. The patches apply cleanly to the linux-mm 5.10.0-rc2 tree. There are a lot of other THP patches being posted. I don't think there are any semantic conflicts but there may be some merge conflicts depending on the order Andrew applies these. Changes in v3: Sent the patch ("mm/thp: fix __split_huge_pmd_locked() for migration PMD") as a separate patch from this series. Rebased to linux-mm 5.10.0-rc2. Changes in v2: Added splitting a THP midway in the migration process: i.e., in migrate_vma_pages().
