From 590a2b5f0a9b740e415e0d52bd8a0f87fc15b87b Mon Sep 17 00:00:00 2001 From: "Vishal Moola (Oracle)" Date: Wed, 4 Jan 2023 13:14:33 -0800 Subject: ceph: convert ceph_writepages_start() to use filemap_get_folios_tag() 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.
