Subject: [PATCH 11/16] drbd: Improved the dec_*() macros
Date: Wed, 31 Aug 2011 17:11:03 +0200 [thread overview]
Message-ID: <1314803468-1201-12-git-send-email-philipp.reisner@linbit.com> (raw)
In-Reply-To: <1314803468-1201-1-git-send-email-philipp.reisner@linbit.com>
Now those can be used with a struct drbd_conf * that has an other
name than 'mdev'.
