This is a well-structured 4-patch series (v9) that enables Transparent Huge Page (THP) support in the DRM pagemap layer for GPU memory migration. The series is logically ordered: first convert to folio-level unlock/put operations, then introduce a helper for zone_device_data access, fix cpages accounting, and finally enable compound page migration. The performance numbers are compelling (7x improvement on 2MB SVM page faults). The code has been through multiple review rounds and carries Reviewed-by tags from Matthew Brost and Balbir Singh.
Overall the series looks solid. I have a few observations, mostly minor, noted below.
