It turns out I want to use folio_put_refs() in two completely different
places (which would likely be in separate pull requests) for 5.18, and
there's a useful place to use it in 5.17, so I'm planning on sending
Linus a pull request for this pair of patches next week.  The reviews
on patch 1 come from the folio GUP reviews over the last week, but I
doubt I've shown patch 2 to anybody before.

Matthew Wilcox (Oracle) (2):
  mm: Add folio_put_refs()
  filemap: Use folio_put_refs() in filemap_free_folio()
