Message

This started out as "I should remove the indirect function call from
freeing compound pages" and turned into "I can free up some space in
struct folio".  So ... what am I bid for the new contents of this word
in the first tail page?

Matthew Wilcox (Oracle) (9):
  io_uring: Stop calling free_compound_page()
  mm: Call the hugetlb destructor directly
  mm: Call free_transhuge_folio() directly from destroy_large_folio()
  mm: Make free_compound_page() static
  mm: Remove free_compound_page()
  mm: Remove HUGETLB_PAGE_DTOR
  mm: Add deferred_list page flag
  mm: Rearrange page flags
  mm: Free up a word in the first tail page
