Message-Id: <20221231150919.659533-7-agruenba@redhat.com> Date: Sat, 31 Dec 2022 16:09:16 +0100 From: Andreas Gruenbacher <agruenba@...hat.com> To: Christoph Hellwig <hch@...radead.org>, "Darrick J . Wong" <djwong@...nel.org>, Alexander Viro <viro@...iv.linux.org.uk>, Matthew Wilcox <willy@...radead.org> Cc: Andreas Gruenbacher <agruenba@...hat.com>, linux-xfs@...r.kernel.org, linux-fsdevel@...r.kernel.org, linux-ext4@...r.kernel.org, cluster-devel@...hat.com Subject: [PATCH v5 6/9] iomap: Rename page_prepare handler to get_folio The ->page_prepare() handler in struct iomap_page_ops is now somewhat misnamed, so rename it to ->get_folio().
