Subject: [PATCH 16/16] drbd: Fixed conn_lowest_minor
Date: Fri,  2 Sep 2011 12:00:48 +0200	[thread overview]
Message-ID: <1314957648-13242-17-git-send-email-philipp.reisner@linbit.com> (raw)
In-Reply-To: <1314957648-13242-1-git-send-email-philipp.reisner@linbit.com>

It actually returned the lowest volume number. While doing that
renamed a few wrongly named variables.
