Subject: [PATCH blktests v3 3/3] nvme/{041,042,043,044,045,048}: Use default hostnqn and hostid
Date:   Mon,  3 Jul 2023 11:16:47 +0200
Message-ID: <20230703091647.800-4-dwagner@suse.de>
In-Reply-To: <20230703091647.800-1-dwagner@suse.de>

The host might have enabled the udev/systemd auto connect feature.
This disturbs the blktests for the fc transport. nvme-cli is able
to distinguish between the different invocations via the --context
option.

Instead creating random generated IDs or reuse the hostnqn, it's safer
to always use the same hostnqn to reduce the risk that the matching
logic doesn't work.
