[PATCH blktests 1/8] nvme/rc: Implement --blkdev none for _nvmet_target_setup()

[Shin'ichiro Kawasaki]

From: Hannes Reinecke <hare at suse.de>

Add an option '--blkdev none' for _nvmet_target_setup() to indicate
that no block devices (and no namespaces) should be created when
setting up the target.
