Subject: [PATCH v2 1/2] mm/vmstat: remove unused folio stat helpers
Date: Wed, 11 Nov 2026 03:34:33 +0000 [thread overview]
Message-ID: <20261111-unused-sym-core-v2-1-3edc7fb8581f@amd.com> (raw)
In-Reply-To: <20261111-unused-sym-core-v2-0-3edc7fb8581f@amd.com>
__zone_stat_add_folio(), __zone_stat_sub_folio(), zone_stat_add_folio(),
__node_stat_add_folio() and __node_stat_sub_folio() have had no callers
since they were added in commit a53e17e4e97b ("mm/vmstat: Add functions
to account folio statistics"). The last zone_stat_sub_folio() user was
removed in commit f1ee018baee9 ("mm: use __page_cache_release() in
folios_put()").
