Subject: [PATCH blktests v2 3/3] nvme/{041,042,043,044,045,048}: Use default hostnqn and hostid
Date:   Wed, 28 Jun 2023 17:16:23 +0200
Message-ID: <20230628151623.11340-4-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. In order to get this working we have to use the default
hostnqn and hostid and not random generated IDs for every single
run.
