Subject: [PATCH 2/3] lockdep: Actually _dec_ in debug_atomic_dec
Date: Tue,  4 May 2010 05:45:35 +0200	[thread overview]
Message-ID: <1272944736-25141-3-git-send-regression-fweisbec@gmail.com> (raw)
In-Reply-To: <1272944736-25141-1-git-send-regression-fweisbec@gmail.com>

Fix a silly copy-paste mistake that was making debug_atomic_dec use
this_cpu_inc instead of this_cpu_dec.
