[PATCH v1 2/2] nvme/047: Test different queue counts

Daniel Wagner
2023-03-20T17:38:27Z

Test if the transport are handling the different queues correctly.

We also issue some I/O to make sure that not just the plain connect
works. For this we have to use a file system which supports direct I/O
and hence we use a device backend.
