The patch 1~2 remove unexpected specific assert for PageTransHuge page.
The Patch 3~6 convert several more migration functions to use folio.
The patch 7 remove PageHead() check to make hugetlb to migrate the
entire hugetlb page instead of -EACCES errno return when
passed the address of a tail page.
The patch 8 cleanup to unify and simplify code a bit in
add_page_for_migration()
v2:
Thanks for all comments and advise from Matthew, Hugh, Zi, Mike, Huang.
- keep page_mapcount() check and remove specific assert for
PageTransHuge page.
- separate patch7 to migrate the entire hugetlb page if a tail page passed,
which unified the behavior between HUGETLB and THP when move_page().
