Subject: [PATCH] device-mapper: Fix target suspension oops.
Date: Tue, 12 Jul 2005 22:24:49 +0100	[thread overview]
Message-ID: <20050712212449.GK12337@agk.surrey.redhat.com> (raw)
In-Reply-To: <20050712140248.3cdcb9b8.akpm@osdl.org>

This section got lost while refactoring the 'Fix deadlocks in core' set 
of patches I sent yesterday.  Without it, you'll have problems
activating any device-mapper devices.

The NULL detection is moved inside the functions instead of every 
caller having to do it.
