android_vh_mm_customize_longterm_pinnable - This hook allows vendors to customize some special folios that are not migrated. They should not be migrated to avoid application lags. android_vh_mm_do_madvise_bypass - This hook allows vendors to customize some madvise behaviors so that some madvise requests can be completed quickly in certain scenarios. android_vh_mm_migrate_one_page - This hook allows vendors to track certain folios that are being migrated. android_vh_mm_remove_migration_pte_bypass - This hook is used to properly handle the migration of the aforementioned special folio. android_vh_mm_split_huge_page_bypass - This hook is used in certain scenarios where large folios should not be split to avoid the overhead caused by splitting. android_vh_mm_try_split_folio_bypass - This hook is used to skip splitting large folios during migration in certain scenarios.
