Subject: [PATCH blktests v2 06/11] nvme/033: Simple test to create and connect to a passthru target
Date: Wed, 30 Sep 2020 12:54:17 -0600	[thread overview]
Message-ID: <20200930185422.11494-7-logang@deltatee.com> (raw)
In-Reply-To: <20200930185422.11494-1-logang@deltatee.com>

This tests creates and connects to a passthru controller backed
by a test NVMe namespace. It then verifies that some common fields
in id-ctrl and id-ns are the same in the target and the orginial
device.
