Message-Id: <20070126054119.A0D12180051@magilla.sf.frob.com> Date: Thu, 25 Jan 2007 21:41:19 -0800 (PST) Sender: linux-kernel-owner@vger.kernel.org X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 605 Lines: 14 I'm not aware of any code in the tree triggering it. We copied some of the uaccess.h macro guts into macros used in systemtap, and there we hit an instance of someone producing code that used a large constant and hit the problem. Since I noticed the kernel code still had the same bug, I was just being proactive in propagating the fix back.
