From 67e5ed969944d7c6d93f658a188240cf60c49f71 Mon Sep 17 00:00:00 2001 From: Arvind Yadav Date: Wed, 6 Sep 2017 16:22:06 -0700 Subject: [PATCH] mm/hugetlb.c: constify attribute_group structures attribute_group are not supposed to change at runtime. All functions working with attribute_group provided by work with const attribute_group. So mark the non-const structs as const.
