Message-Id: <20061122001146.95a56c72.kernel@irasnyder.com>
Date: Wed, 22 Nov 2006 00:11:46 -0800
From: Ira Snyder <kernel@...snyder.com>
To: linux-kernel@...r.kernel.org
Subject: [PATCH] sparse fix: add many lock annotations
[PATCH] sparse fix: add many lock annotations
This patch adds many lock annotations to the kernel source to quiet
warnings from sparse. In almost every case, it quiets the warning caused
by locks that are intentionally grabbed in one function and released in
another.
In the other cases, __acquire() and __release() are used to make sparse
believe that a lock was grabbed (even though it was not), in order to
make all exit points have equal lock counts. These follow the style in
kernel/sched.c.
