X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=adfd6da2be304900011d841b6c09f18e3892d3e8;p=ceph-client.git

ceph: redirty the page for wirtepage if fails

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().
