Subject: [PATCH] ceph: redirty the page for wirtepage if fails
Date: Sun, 24 Apr 2022 17:39:24 +0800	[thread overview]
Message-ID: <20220424093924.32691-1-xiubli@redhat.com> (raw)

When run out of memories we should redirty the page before failing
the writepage. Or we will hit BUG_ON(folio_get_private(folio)) in
ceph_dirty_folio().
