Subject: [PATCH v2 11/46] mm/memcg: Remove 'page' parameter to mem_cgroup_charge_statistics()
Date: Tue, 22 Jun 2021 13:15:16 +0100	[thread overview]
Message-ID: <20210622121551.3398730-12-willy@infradead.org> (raw)
In-Reply-To: <20210622121551.3398730-1-willy@infradead.org>

The last use of 'page' was removed by commit 468c398233da ("mm:
memcontrol: switch to native NR_ANON_THPS counter"), so we can now remove
the parameter from the function.
