Subject: [PATCH] IB/hfi1: constify vm_operations_struct
Date: Mon, 28 Aug 2017 09:59:28 +0530 [thread overview]
Message-ID: <8fa5bd3197b755de927ef5c3ae431e588a3a7d91.1503894254.git.arvind.yadav.cs@gmail.com> (raw)
vm_operations_struct are not supposed to change at runtime.
vm_area_struct structure working with const vm_operations_struct.
So mark the non-const vm_operations_struct structs as const.
