Subject: [PATCH 06/20] btrfs: Convert btree_migratepage to migrate_folio
Date: Mon, 6 Jun 2022 21:40:36 +0100 [thread overview]
Message-ID: <20220606204050.2625949-7-willy@infradead.org> (raw)
In-Reply-To: <20220606204050.2625949-1-willy@infradead.org>
Use a folio throughout this function. migrate_page() will be converted
later.
