Hi Dan
I applied the patch to v5.10-rc3 ~ v5.10-rc6, and cannot reproduce this issue with my regression test now, feel free to add:diff --git a/arch/x86/mm/pgtable.c b/arch/x86/mm/pgtable.c index dfd82f51ba66..7ed99314dcdf 100644 --- a/arch/x86/mm/pgtable.c +++ b/arch/x86/mm/pgtable.c @@ -829,6 +829,7 @@ int pud_free_pmd_page(pud_t *pud, unsigned long addr) }free_page((unsigned long)pmd_sv); + pgtable_pmd_page_dtor(virt_to_page(pmd)); free_page((unsigned long)pmd); return 1; In 2013 Kirill noticed that he missed a pmd page table free site: c283610e44ec x86, mm: do not leak page->ptl for pmd page tables In 2018 Toshi added a new pmd page table free site without the destructor: 28ee90fe6048 x86/mm: implement free pmd/pte page interfaces In 2020 Willy adds PG_table accounting that flags the missing pgtable_pmd_page_dtor() Yi, I would appreciate a confirmation that the fix works for you.
