Subject: [PATCH blktests 06/11] nvme/033: Simple test to create and connect to a passthru target
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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.
