From 82ab55ebccc81a3611a87f028db0abbecf02d9bd Mon Sep 17 00:00:00 2001 From: Michel Lespinasse Date: Mon, 24 Jan 2022 17:43:53 -0800 Subject: [PATCH] FROMLIST: do_anonymous_page: use update_mmu_tlb() update_mmu_tlb() can be used instead of update_mmu_cache() when the page fault handler detects that it lost the race to another page fault. It looks like this one call was missed in https://patchwork.kernel.org/project/linux-mips/patch/1590375160-6997-2-git-send-email-maobibo@loongson.cn after Andrew asked to replace all update_mmu_cache() calls with an alias in the previous version of this patch here: https://patchwork.kernel.org/project/linux-mips/patch/1590031837-9582-2-git-send-email-maobibo@loongson.cn/#23374625 Signed-off-by: Michel Lespinasse Link: https://lore.kernel.org/all/20220128131006.67712-5-michel@lespinasse.org/ Bug: 161210518 Signed-off-by: Suren Baghdasaryan Change-Id: Iaad4d3c27e12c2d9bf68d1140709788fc8dead24 --- mm/memory.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/memory.c b/mm/memory.c index 9a3b21369503..4adba986febd 100644 --- a/mm/memory.c +++ b/mm/memory.c @@ -3792,7 +3792,7 @@ static vm_fault_t do_anonymous_page(struct vm_fault *vmf) vmf->pte = pte_offset_map_lock(vma->vm_mm, vmf->pmd, vmf->address, &vmf->ptl); if (!pte_none(*vmf->pte)) { - update_mmu_cache(vma, vmf->address, vmf->pte); + update_mmu_tlb(vma, vmf->address, vmf->pte); goto release; }
