David Hildenbrand 0cf459866a mm/gup: use gup_can_follow_protnone() also in GUP-fast ... There seems to be no reason why FOLL_FORCE during GUP-fast would have to fallback to the slow path when stumbling over a PROT_NONE mapped page. We only have to trigger hinting faults in case FOLL_FORCE is not set, and any kind of fault handling naturally happens from the slow path -- where NUMA hinting accounting/handling would be performed. Note that the comment regarding THP migration is outdated: commit 2b4847e730 ("mm: numa: serialise parallel get_user_page against THP migration") described that this was required for THP due to lack of PMD migration entries. Nowadays, we do have proper PMD migration entries in place -- see set_pmd_migration_entry(), which does a proper pmdp_invalidate() when placing the migration entry. So let's just reuse gup_can_follow_protnone() here to make it consistent and drop the somewhat outdated comments.
