The quilt patch titled Subject: mm: hugetlb_vmemmap: simplify hugetlb_vmemmap_init() a bit has been removed from the -mm tree. Its filename was mm-hugetlb_vmemmap-simplify-hugetlb_vmemmap_init-a-bit.patch This patch was dropped because it was merged into the mm-stable branch of git://git.kernel.org/pub/scm/linux/kernel/git/akpm/mm ------------------------------------------------------ From: Muchun Song <songmuchun@xxxxxxxxxxxxx> Subject: mm: hugetlb_vmemmap: simplify hugetlb_vmemmap_init() a bit Date: Thu, 23 Feb 2023 14:59:47 +0800 The check of IS_ENABLED(CONFIG_PROC_SYSCTL) is unnecessary since register_sysctl_init() will be empty in this case. So, there is no warnings after removing the check.
