From 30152245c63b59f835193b37212991bc24669645 Mon Sep 17 00:00:00 2001 From: Muchun Song Date: Tue, 28 Jun 2022 17:22:32 +0800 Subject: [PATCH] mm: hugetlb_vmemmap: replace early_param() with core_param() After the following commit: 78f39084b41d ("mm: hugetlb_vmemmap: add hugetlb_optimize_vmemmap sysctl") There is no order requirement between the parameter of "hugetlb_free_vmemmap" and "hugepages" since we have removed the check of whether HVO is enabled from hugetlb_vmemmap_init(). Therefore we can safely replace early_param() with core_param() to simplify the code.
