Date: Wed, 2 Nov 2022 09:10:15 -0700 From: "Vishal Moola (Oracle)" <vishal.moola@...il.com> To: linux-fsdevel@...r.kernel.org Cc: linux-afs@...ts.infradead.org, linux-kernel@...r.kernel.org, linux-btrfs@...r.kernel.org, ceph-devel@...r.kernel.org, linux-cifs@...r.kernel.org, linux-ext4@...r.kernel.org, linux-f2fs-devel@...ts.sourceforge.net, cluster-devel@...hat.com, linux-nilfs@...r.kernel.org, linux-mm@...ck.org, "Vishal Moola (Oracle)" <vishal.moola@...il.com>, David Sterba <dsterba@...e.com> Subject: [PATCH v4 07/23] btrfs: Convert extent_write_cache_pages() to use filemap_get_folios_tag() Converted function to use folios throughout. This is in preparation for the removal of find_get_pages_range_tag(). Now also supports large folios.
