Subject: [PATCH blktests 10/11] nvme/037: Add test which loops passthru connect and disconnect
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Similar to test nvme/031 except for passthru controllers.

Note: it's normal to get I/O errors in this test as
when the controller disconnects it races with the partition
table read.
