This patch series converts migrate_page_add() and queue_pages_required() to migrate_folio_add() and queue_page_required(). It also converts the callers of the functions to use folios as well, and introduces a helper function to estimate a folio's mapcount. --- v3: - Move folio_estimated_mapcount() to fix build warnings - Add comments to folio_estimated_mapcount() to make its function and purpose clear v2: - Introduce folio_estimated_mapcount() to replace page_mapcount() in migrate_page_add() and queue_pages_hugetlb(). - Elaborate on the comments to make it clear what the mapcount check is for and why it is being done this way.
