Subject: [PATCH v3 0/5] mm: cleanup and use more folio in page fault

Rename page_copy_prealloc() to folio_prealloc(), which is used by
more functions, also do more folio conversion in page fault.

- drop patch6 as Small-sized THP for anon will change anon allocation
- correct do_cow_page to do_cow_fault in subject and changlog
- add RB of Vishal

v2:
- add folio_test_large check in ksm_might_need_to_copy() and
  replace page->index to folio->index, per David, Matthew
- add RB of Sidhartha

Kefeng Wang (5):
  mm: ksm: use more folio api in ksm_might_need_to_copy()
  mm: memory: use a folio in validate_page_before_insert()
  mm: memory: rename page_copy_prealloc() to folio_prealloc()
  mm: memory: use a folio in do_cow_fault()
  mm: memory: use folio_prealloc() in wp_page_copy()
