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 <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>
