Subject: [PATCH rfc 00/18] mm: convert to use folio mm counter

Convert mm counter page functions to folio ones.

  mm_counter()       ->	mm_counter_folio()
  mm_counter_file()  ->	mm_counter_file_folio()

Maybe it's better to rename folio mm counter function back to mm_counter()
and mm_counter_file() after all conversion?

Kefeng Wang (18):
  mm: add mm_counter_folio() and mm_counter_file_folio()
  uprobes: use mm_counter_file_folio()
  mm: userfaultfd: use mm_counter_folio()
  mm: rmap: use mm_counter_[file]_folio()
  mm: swap: introduce pfn_swap_entry_to_folio()
  mm: huge_memory: use a folio in __split_huge_pmd_locked()
  mm: huge_memory: use a folio in zap_huge_pmd()
  mm: khugepaged: use mm_counter_file_folio() in
    collapse_pte_mapped_thp()
  mm: memory: use a folio in do_set_pmd()
  mm: memory: use mm_counter_file_folio() in copy_present_pte()
  mm: memory: use mm_counter_file_folio() in wp_page_copy()
  mm: memory: use mm_counter_file_folio() in set_pte_range()
  mm: memory: use a folio in insert_page_into_pte_locked()
  mm: remove mm_counter_file()
  mm: memory: use a folio in copy_nonpresent_pte()
  mm: use a folio in zap_pte_range()
  s390: pgtable: use mm_counter_folio() in ptep_zap_swap_entry()
  mm: remove mm_counter()
