Hi all, Today's linux-next merge of the mm-stable tree got a conflict in: mm/hugetlb.c between commit: 5596d9e8b553 ("mm/hugetlb: fix potential race in __update_and_free_hugetlb_folio()") from Linus' tree and commit: a81fa1dc5db2 ("mm/hugetlb: fix potential race with try_memory_failure_hugetlb()") from the mm-stable tree. I fixed it up (see below) and can carry the fix as necessary. This is now fixed as far as linux-next is concerned, but any non trivial conflicts should be mentioned to your upstream maintainer when your tree is submitted for merging. You may also want to consider cooperating with the maintainer of the conflicting tree to minimise any particularly complex conflicts. -- Cheers, Stephen Rothwell diff --cc mm/hugetlb.c index 43e1af868cfd,740df0b377aa..000000000000 --- a/mm/hugetlb.c +++ b/mm/hugetlb.c @@@ -1725,6 -1722,20 +1722,13 @@@ static void __update_and_free_hugetlb_f return; } + /* + * If we don't know which subpages are hwpoisoned, we can't free + * the hugepage, so it's leaked intentionally. + */ + if (folio_test_hugetlb_raw_hwp_unreliable(folio)) + return; + - /* - * Move PageHWPoison flag from head page to the raw error pages, - * which makes any healthy subpages reusable. - */ - if (unlikely(folio_test_hwpoison(folio))) - folio_clear_hugetlb_hwpoison(folio); - /* * If vmemmap pages were allocated above, then we need to clear the * hugetlb flag under the hugetlb lock.
