[PATCH 0/7] khugepaged folio conversions

["Matthew Wilcox (Oracle)" <willy@infradead.org>]

We've been kind of hacking piecemeal at converting khugepaged to use
folios instead of compound pages, and so this patchset is a little
larger than it should be as I undo some of our wrong moves in the past.
In particular, collapse_file() now consistently uses 'new_folio' for the
freshly allocated folio and 'folio' for the one that's currently in use.

Matthew Wilcox (Oracle) (7):
  khugepaged: Inline hpage_collapse_alloc_folio()
  khugepaged: Convert alloc_charge_hpage to alloc_charge_folio
  khugepaged: Remove hpage from collapse_huge_page()
  khugepaged: Pass a folio to __collapse_huge_page_copy()
  khugepaged: Remove hpage from collapse_file()
  khugepaged: Use a folio throughout collapse_file()
  khugepaged: Use a folio throughout hpage_collapse_scan_file()
