[Barry Song]

From: Barry Song <baohua@xxxxxxxxxx>

-v2:
 * lots of cleanup for patch 2/3: renaming, moving data
   structures, and using const properly
 * collected tags from Kairui, Nhat and Barry

-v1:
 https://lore.kernel.org/linux-mm/20260302104016.163542-1-bhe@xxxxxxxxxx/

This can simplify the code logic and benefit any new type of swap device
added later.

And also do renaming in this patchset:
-------
   file renaming:
   ---
   mm/page_io.c to mm/swap_io.c

   function renaming:
   ---
   swap_writepage_* to swap_write_folio_* in file mm/swap_io.c

Baoquan He (3):
  mm/swap: rename mm/page_io.c to mm/swap_io.c
  mm/swap: use swap_ops to register swap device's methods
  mm/swap_io.c: rename swap_writepage_* to swap_write_folio_*
