Subject: [PATCH tip/core/rcu 4/8] kernel: Removing undead ifdef CONFIG_DEBUG_LOCK_ALLOC
Date: Wed, 22 Sep 2010 17:50:49 -0700	[thread overview]
Message-ID: <1285203053-22068-4-git-send-email-paulmck@linux.vnet.ibm.com> (raw)
In-Reply-To: <20100923005033.GA22006@linux.vnet.ibm.com>

From: Christian Dietrich <qy03fugy@stud.informatik.uni-erlangen.de>

The CONFIG_DEBUG_LOCK_ALLOC ifdef isn't necessary at this point, because it is
checked in an outer ifdef level already and has no effect here.
