Subject: [PATCH v7 03/28] mm: Add folio_pgdat and folio_zone
Date: Fri, 9 Apr 2021 19:50:40 +0100 [thread overview]
Message-ID: <20210409185105.188284-4-willy@infradead.org> (raw)
In-Reply-To: <20210409185105.188284-1-willy@infradead.org>
These are just convenience wrappers for callers with folios; pgdat and
zone can be reached from tail pages as well as head pages.
