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

[Kefeng Wang <wangkefeng.wang@huawei.com>]

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()
