The following hooks are added for memory reclaim tuning: android_vh_mm_isolate_priv_lru - This hook is used to properly handle certain folios when they are reclaimed. android_vh_mm_customize_file_is_tiny - For a specific process, we want only anonymous pages to be reclaimed. This hook allows vendors to modify the value of file_is_tiny to affect the reclaim behavior. android_vh_mm_customize_pgdat_balanced - When there are multiple zones, it is not always reasonable to perform indirect reclaim only when all zones do not meet the watermark. This hook allows vendors to customize pgdat_balanced to use their own strategy to determine whether to perform and stop indirect collection. android_vh_mm_customize_reclaim_idx - When there are multiple zones, vendors use this hook to customize which zones can be reclaimed. android_vh_mm_customize_zone_can_compact - When there are multiple zones, vendors use this hook to customize which zones can be compacted.
