Subject: [PATCH 4/5] mm: huge_memory: constify attribute_group structures.
Date: Thu, 27 Jul 2017 17:37:20 +0530 [thread overview]
Message-ID: <1501157240-3876-1-git-send-email-arvind.yadav.cs@gmail.com> (raw)
attribute_group are not supposed to change at runtime. All functions
working with attribute_group provided by <linux/sysfs.h> work with
const attribute_group. So mark the non-const structs as const.
