Date: Thu, 27 Jul 2017 17:37:40 +0530 Message-Id: <1501157260-3922-1-git-send-email-arvind.yadav.cs@gmail.com> Sender: owner-linux-mm@kvack.org List-ID: To: akpm@linux-foundation.org, mhocko@suse.com, n-horiguchi@ah.jp.nec.com, mike.kravetz@oracle.com, khandual@linux.vnet.ibm.com, aarcange@redhat.com, gerald.schaefer@de.ibm.com Cc: linux-mm@kvack.org, linux-kernel@vger.kernel.org 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.
