Subject: [PATCH v1 0/6] Anon rmap cleanups

Some cleanups around rmap for anon pages. I'm working on more cleanups
also around file rmap -- also to handle the "compound" parameter
internally only and to let hugetlb use page_add_file_rmap(), but these
changes make sense separately.

David Hildenbrand (6):
  mm/rmap: drop stale comment in page_add_anon_rmap and
    hugepage_add_anon_rmap()
  mm/rmap: move SetPageAnonExclusive out of __page_set_anon_rmap()
  mm/rmap: move folio_test_anon() check out of __folio_set_anon()
  mm/rmap: warn on new PTE-mapped folios in page_add_anon_rmap()
  mm/rmap: simplify PageAnonExclusive sanity checks when adding anon
    rmap
  mm/rmap: pass folio to hugepage_add_anon_rmap()
