[PATCH 1/8] mm/vmstat: remove unused folio stat helpers

[Shivank Garg]

__zone_stat_add_folio(), __zone_stat_sub_folio(), zone_stat_add_folio(),
zone_stat_sub_folio(), __node_stat_add_folio() and __node_stat_sub_folio()
have no callers.  The last zone_stat_sub_folio() user was removed in
commit f1ee018baee9 ("mm: use __page_cache_release() in folios_put()").
