Subject: [PATCH v3 12/25] mm/memcg: Add mem_cgroup_folio_lruvec
Date: Thu, 28 Jan 2021 07:03:51 +0000	[thread overview]
Message-ID: <20210128070404.1922318-13-willy@infradead.org> (raw)
In-Reply-To: <20210128070404.1922318-1-willy@infradead.org>

mem_cgroup_page_lruvec() already expects a head page, so this will add some
typesafety once we can remove mem_cgroup_page_lruvec().
