Date: Fri, 30 May 2008 17:34:58 -0700 [thread overview]
Message-ID: <20080531003458.GD6208@suse.de> (raw)
In-Reply-To: <20080531003214.GA6208@suse.de>
This primarily looks like coding style cleanup, removing some typedefs
and fixing lines that are longer than 80 characters.
If there are any real code changes in here, I didn't notice them.
