Subject: [PATCH 6/6] nvme: display correct subsystem NQN
Date: Tue, 21 Sep 2021 17:15:29 +0200 [thread overview]
Message-ID: <20210921151529.29419-7-hare@suse.de> (raw)
In-Reply-To: <20210921151529.29419-1-hare@suse.de>
With discovery controllers supporting unique subsystem NQNs the
actual subsystem NQN might be different from that one passed in
via the connect args. So add a helper to display the resulting
subsystem NQN.
