mainline inclusion from mainline-v6.7-rc1 commit 80203f1ca086835100843f1474bd6dd4a48cc73b category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/IAR7B3 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... -------------------------------- 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 free_bootmem_page(). In debug mode, there are following warning: kmemleak: Partially freeing unknown object at 0xffff97345aff7000 (size 4096) Link: https://lkml.kernel.org/r/20231018102952.3339837-3-liushixin2@huawei.com Fixes: 028725e73375 ("bootmem: remove the vmemmap pages from kmemleak in free_bootmem_page") Signed-off-by: Liu Shixin <liushixin2@huawei.com> Acked-by: Catalin Marinas <catalin.marinas@arm.com> Cc: Kefeng Wang <wangkefeng.wang@huawei.com> Cc: Patrick Wang <patrick.wang.shcn@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Liu Shixin <liushixin2@huawei.com> --- include/linux/bootmem_info.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/include/linux/bootmem_info.h b/include/linux/bootmem_info.h index 888eb660d3f6a..7395db4f44b09 100644 --- a/include/linux/bootmem_info.h +++ b/include/linux/bootmem_info.h @@ -60,7 +60,7 @@ static inline void get_page_bootmem(unsigned long info, struct page *page, static inline void free_bootmem_page(struct page *page) { - 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); } #endif -- 2.34.1
