Message-Id: <20230919045135.3635437-1-willy@infradead.org> Date: Tue, 19 Sep 2023 05:51:09 +0100 From: "Matthew Wilcox (Oracle)" <willy@...radead.org> To: Andrew Morton <akpm@...ux-foundation.org> Cc: "Matthew Wilcox (Oracle)" <willy@...radead.org>, linux-fsdevel@...r.kernel.org, gfs2@...ts.linux.dev, linux-nilfs@...r.kernel.org, linux-ntfs-dev@...ts.sourceforge.net, ntfs3@...ts.linux.dev, ocfs2-devel@...ts.linux.dev, reiserfs-devel@...r.kernel.org, linux-ext4@...r.kernel.org, Pankaj Raghav <p.raghav@...sung.com> Subject: [PATCH 00/26] Finish the create_empty_buffers() transition Pankaj recently added folio_create_empty_buffers() as the folio equivalent to create_empty_buffers(). This patch set finishes the conversion by first converting all remaining filesystems to call folio_create_empty_buffers(), then renaming it back to create_empty_buffers(). I took the opportunity to make a few simplifications like making folio_create_empty_buffers() return the head buffer and extracting get_nth_bh() from nilfs2. A few of the patches in this series aren't directly related to create_empty_buffers(), but I saw them while I was working on this and thought they'd be easy enough to add to this series. Compile-tested only, other than ext4.
