[PATCH 0/4] mm, ceph: remove wait_on_page_writeback()

wait_on_page_writeback() is a compatibility wrapper for
folio_wait_writeback() and has a single remaining caller in ceph's
writeback path. Convert that caller to use folios and remove the
wrapper.

Along the way, replace ceph's page_snap_context(), which uses
page->private, with a folio-based ceph_folio_snap_context(), dropping
three &folio->page conversions at its call sites.

No functional change intended.

Note: This is currently based on mm-new. It may conflict slightly with
Zi Yan's series "Remove PG_private by using page/folio->private checks
instead" [1], which should allow simplifying ceph_folio_snap_context()
further.
