Subject: [PATCH v5 08/23] ceph: Convert ceph_writepages_start() to use filemap_get_folios_tag()
Date: Wed, 4 Jan 2023 13:14:33 -0800 [thread overview]
Message-ID: <20230104211448.4804-9-vishal.moola@gmail.com> (raw)
In-Reply-To: <20230104211448.4804-1-vishal.moola@gmail.com>
Convert function to use a folio_batch instead of pagevec. This is in
preparation for the removal of find_get_pages_range_tag().
Also some minor renaming for consistency.
