Subject: [PATCH 0/5] remove page_endio()

It was decided to remove the page_endio() as per the previous RFC
discussion[1] of this series and move that functionality into the caller
itself. One of the side benefit of doing that is the callers have been
modified to directly work on folios as page_endio() already worked on
folios.

mpage changes were tested with a simple boot testing. orangefs was
tested by Mike Marshall (No code changes since he tested). Zram was
only build tested. No functional changes were introduced as a part of
this AFAIK.

Changes since RFC 2[2]:
- Call bio_put in zram bio end io handler (Still not Acked by hch[3])
- Call folio_set_error in mpage read endio error path (Willy)
- Directly call folio->mapping in mpage write endio error path (Willy)

Pankaj Raghav (5):
  zram: remove the call to page_endio in the bio end_io handler
  orangefs: use folios in orangefs_readahead
  mpage: split bi_end_io callback for reads and writes
  mpage: use folios in bio end_io handler
  filemap: remove page_endio()
