Date: Mon, 13 Jun 2022 07:37:14 +0200 From: Christoph Hellwig <hch@....de> To: Matthew Wilcox <willy@...radead.org>, Jan Kara <jack@...e.com>, Dave Kleikamp <shaggy@...nel.org>, Konstantin Komarov <almaz.alexandrovich@...agon-software.com> Cc: linux-ext4@...r.kernel.org, linux-fsdevel@...r.kernel.org, linux-kernel@...r.kernel.org, jfs-discussion@...ts.sourceforge.net, ntfs3@...ts.linux.dev Subject: [PATCH 5/6] fs: don't call ->writepage from __mpage_writepage All callers of mpage_writepage use block_write_full_page as their ->writepage implementation when called from mpage_writepages (although for ntfs3 this is obsfucated a bit). Just call block_write_full_page directly instead of going through the ->writepage indirection.
