[PATCH v2 1/8] mm: migrate: remove PageTransHuge check in numamigrate_isolate_page()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since we begin to convert the numa migration code to use folio, which
could let us to handle arbitrary sizes of folio, so drop assert that
we only support PageTransHuge page(PMD size) when order > 0.
