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@xxxxxxxxxx Link: https://lkml.kernel.org/r/20231018102952.3339837-2-liushixin2@xxxxxxxxxx Fixes: dd0ff4d12dd2 ("bootmem: remove the vmemmap pages from kmemleak in put_page_bootmem") Signed-off-by: Liu Shixin <liushixin2@xxxxxxxxxx> Acked-by: Catalin Marinas <catalin.marinas@xxxxxxx> Cc: Kefeng Wang <wangkefeng.wang@xxxxxxxxxx> Cc: Patrick Wang <patrick.wang.shcn@xxxxxxxxx> Signed-off-by: Andrew Morton <akpm@xxxxxxxxxxxxxxxxxxxx> --- mm/bootmem_info.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) --- a/mm/bootmem_info.c~bootmem-use-kmemleak_free_part_phys-in-put_page_bootmem +++ a/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); } } _ Patches currently in -mm which might be from liushixin2@xxxxxxxxxx are mm-vmscan-try-to-reclaim-swapcache-pages-if-no-swap-space.patch mm-vmscan-try-to-reclaim-swapcache-pages-if-no-swap-space-v6.patch bootmem-use-kmemleak_free_part_phys-in-put_page_bootmem.patch bootmem-use-kmemleak_free_part_phys-in-free_bootmem_page.patch mm-kmemleak-fix-print-format-of-pointer-in-pr_debug.patch mm-kmemleak-split-__create_object-into-two-functions.patch mm-kmemleak-use-mem_pool_free-to-free-object.patch mm-kmemleak-add-__find_and_remove_object.patch mm-kmemleak-fix-partially-freeing-unknown-object-warning.patch
