Subject: [PATCH v2 0/7] mm: remove cgroup_throttle_swaprate() completely

Convert all the caller functions of cgroup_throttle_swaprate() to use
folios, and use folio_throttle_swaprate(),  which allows us to remove
cgroup_throttle_swaprate() completely.

v2:
- address comments from Matthew Wilcox, eg, 
  1) folio conversion inside  __do_huge_pmd_anonymous_page() function,
  2) rename __cgroup_throttle_swaprate() to __folio_throttle_swaprate()
  3) rename gfp_mask to gfp

Kefeng Wang (7):
  mm: huge_memory: convert __do_huge_pmd_anonymous_page() to use a folio
  mm: memory: use folio_throttle_swaprate() in do_swap_page()
  mm: memory: use folio_throttle_swaprate() in page_copy_prealloc()
  mm: memory: use folio_throttle_swaprate() in wp_page_copy()
  mm: memory: use folio_throttle_swaprate() in do_anonymous_page()
  mm: memory: use folio_throttle_swaprate() in do_cow_fault()
  mm: swap: remove unneeded cgroup_throttle_swaprate()
