Message-Id: <20080603215543.3230026FC96@magilla.localdomain> Date: Tue, 3 Jun 2008 14:55:43 -0700 (PDT) Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 724 Lines: 16 I like all three of these changes. The 1/3 and 2/3 together constitute a fix for the coredump vs aio race that is nice and clean. The 2/2 is all cleanup or possibly fixes more arcane cases we haven't enumerated yet. (I would have made that the last patch of the three.) It merits some follow-up looking at all (!task->mm) sorts of tests and making them use a helper for what they really mean to express (e.g. is_kernel_thread() if that's what they intend).
