These patches all interact in annoying ways which make it tricky to send them out in any way other than a big batch, even though there's not really an overarching theme to connect them. The big effects of this patch series are: - folio_test_hugetlb() becomes reliable, even when called without a page reference - We free up PG_slab, and we could always use more page flags - We no longer need to check PageSlab before calling page_mapcount() Matthew Wilcox (Oracle) (9): mm: Always initialise folio->_deferred_list mm: Create FOLIO_FLAG_FALSE and FOLIO_TYPE_OPS macros mm: Remove folio_prep_large_rmappable() mm: Support page_mapcount() on page_has_type() pages mm: Turn folio_test_hugetlb into a PageType mm: Remove a call to compound_head() from is_page_hwpoison() mm: Free up PG_slab mm: Improve dumping of mapcount and page_type hugetlb: Remove mention of destructors fs/proc/page.c | 7 +- include/linux/huge_mm.h | 3 - include/linux/mm.h | 8 +- include/linux/page-flags.h | 172 ++++++++++++++++++++------------- include/trace/events/mmflags.h | 3 +- mm/debug.c | 19 ++-- mm/huge_memory.c | 11 +-- mm/hugetlb.c | 65 ++++--------- mm/internal.h | 5 +- mm/memcontrol.c | 2 + mm/memory-failure.c | 9 -- mm/page_alloc.c | 9 +- mm/slab.h | 2 +- 13 files changed, 155 insertions(+), 160 deletions(-) -- 2.43.0
