From 6d4e2cda62af38f7c21052b6847ffff08ea7173f Mon Sep 17 00:00:00 2001 From: Liu Shixin Date: Wed, 18 Oct 2023 18:29:46 +0800 Subject: [PATCH] bootmem: use kmemleak_free_part_phys in put_page_bootmem Patch series "Some bugfix about kmemleak", v3. Some bugfixes for kmemleak and the printed info from debug mode. This patch (of 7): Since kmemleak_alloc_phys() rather than kmemleak_alloc() was called from memblock_alloc_range_nid(), kmemleak_free_part_phys() should be used to delete kmemleak object in put_page_bootmem(). In debug mode, there are following warning: kmemleak: Partially freeing unknown object at 0xffff97345aff7000 (size 4096) Link: https://lkml.kernel.org/r/20231018102952.3339837-1-liushixin2@huawei.com Link: https://lkml.kernel.org/r/20231018102952.3339837-2-liushixin2@huawei.com Fixes: dd0ff4d12dd2 ("bootmem: remove the vmemmap pages from kmemleak in put_page_bootmem") Signed-off-by: Liu Shixin Acked-by: Catalin Marinas Cc: Kefeng Wang Cc: Patrick Wang Signed-off-by: Andrew Morton --- mm/bootmem_info.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/mm/bootmem_info.c b/mm/bootmem_info.c index b1efebfcf94b..fa7cb0c87c03 100644 --- a/mm/bootmem_info.c +++ b/mm/bootmem_info.c @@ -34,7 +34,7 @@ void put_page_bootmem(struct page *page) ClearPagePrivate(page); set_page_private(page, 0); INIT_LIST_HEAD(&page->lru); - kmemleak_free_part(page_to_virt(page), PAGE_SIZE); + kmemleak_free_part_phys(PFN_PHYS(page_to_pfn(page)), PAGE_SIZE); free_reserved_page(page); } }
