Subject: [PATCH 02/38] drbd: Remove pointless check
Date: Wed, 25 Nov 2015 11:53:35 +0100 [thread overview]
Message-ID: <1448448851-10343-3-git-send-email-philipp.reisner@linbit.com> (raw)
In-Reply-To: <1448448851-10343-1-git-send-email-philipp.reisner@linbit.com>
In drbd-8.4 there is always a single connection per resource,
and there is always exactly one peer_device for a device.
peer_device can not be NULL here.
