[PATCH blktests 06/11] nvme/033: Simple test to create and connect to a passthru target

From: Logan Gunthorpe
Date: Thu Aug 27 2020 - 15:50:20 EST


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.
