Thanks for the reminder, this fell through cracks. It indeed appears that I can move mm-create-folio_flag_false-and-folio_type_ops-macros.patch mm-support-page_mapcount-on-page_has_type-pages.patch mm-turn-folio_test_hugetlb-into-a-pagetype.patch mm-turn-folio_test_hugetlb-into-a-pagetype-fix.patch without merge or build issues. I added Fixes: 9c5ccf2db04b ("mm: remove HUGETLB_PAGE_DTOR") Cc: to all patches. But a question: 9c5ccf2db04b is from August 2023. Why are we seeing this issue now?
