------------------------------------------------------ From: Liu Shixin liushixin2@huawei.com Subject: bootmem: remove the vmemmap pages from kmemleak in free_bootmem_page Date: Tue, 4 Jul 2023 18:19:42 +0800

commit dd0ff4d12dd2 ("bootmem: remove the vmemmap pages from kmemleak in put_page_bootmem") fix an overlaps existing problem of kmemleak. But the problem still existed when HAVE_BOOTMEM_INFO_NODE is disabled, because in this case, free_bootmem_page() will call free_reserved_page() directly.

Fix the problem by adding kmemleak_free_part() in free_bootmem_page() when HAVE_BOOTMEM_INFO_NODE is disabled.
