Subject: [PATCH 0/3] mm,thp,rmap: rework the use of subpages_mapcount
Linus was underwhelmed by the earlier compound mapcounts series:
this series builds on top of it (as in next-20221117) to follow
up on his suggestions - except rmap.c still using lock_page_memcg(),
since I hesitate to steal the pleasure of deletion from Johannes.
1/3 mm,thp,rmap: subpages_mapcount of PTE-mapped subpages
2/3 mm,thp,rmap: subpages_mapcount COMPOUND_MAPPED if PMD-mapped
3/3 mm,thp,rmap: clean up the end of __split_huge_pmd_locked()
