Message-ID: <20090927184201.GA12402@x200>
Date: Sun, 27 Sep 2009 22:42:01 +0400
From: Alexey Dobriyan <adobriyan@...il.com>
To: torvalds@...ux-foundation.org, akpm@...ux-foundation.org
Cc: linux-mm@...ck.org, linux-kernel@...r.kernel.org
Subject: [PATCH] const: mark struct vm_struct_operations
* mark struct vm_area_struct::vm_ops as const
* mark vm_ops in AGP code
But leave TTM code alone, something is fishy there with global vm_ops
being used.
