[PATCH mm-unstable v1 0/4] mm/swap: stop using page->private on tail pages for THP_SWAP + cleanups

[David Hildenbrand <david@redhat.com>]

This series stops using page->private on tail pages for THP_SWAP,
replaces folio->private by folio->swap for swapcache folios, and starts
using "new_folio" for tail pages that we are splitting to remove the usage
of page->private for swapcache handling completely.

@Willy, I added your SOB on patch #2 from [1], hoping that's ok.
