[PATCH v2 0/7] mm: remove page idle and young wrapper

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

Convert to use folio idle and young functions instead of page ones,
then remove all page idle and young wrapper.

v2:
- remove useless PageTail && PageSlab check 
- collect Gregory Price's work, see patch3

Kefeng Wang (7):
  fs/proc/page: remove unneeded PageTail && PageSlab check
  fs/proc/page: use a folio in stable_page_flags()
  fs/proc/page: respect folio head-page flag placement
  mm: huge_memory: use more folio api in __split_huge_page_tail()
  mm: task_mmu: use a folio in smaps_account()
  mm: task_mmu: use a folio in clear_refs_pte_range()
  page_idle: kill page idle and young wrapper
