[PATCH blktests 3/3] nvme: add test for resetting the loopback controller

[ckulkarnilinux@gmail.com (chaitany kulkarni)]

Hi Johannes,

Thanks for submitting the test.

I was wondering if we can move the generic setup and clean up
functionality to the helpers for reference:-

+pre()
+{
+      # Clean up all stale modules
+       modprobe -r nvme-loop
+       modprobe -r nvme-core
+       modprobe -r nvmet
+
}

+post()
+{
+       modprobe -r nvme-loop
+       modprobe -r nvme-core
+       modprobe -r nvmet
+
+}

+test() {
+       echo "Running ${TEST_NAME}"
+
+       pre
+
+       modprobe nvme-core multipath=1
+       modprobe nvmet
+       modprobe nvme-loop
+
+       local port
+       port=$(_create_nvmet_port "loop")
+
+       truncate -s 1G "$TMPDIR/img"
+
+       local loop_dev
+       loop_dev="$(losetup -f --show "$TMPDIR/img")"
+
+       _create_nvmet_subsystem "blktests-subsystem-1" "${loop_dev}" \
+               "91fdba0d-f87b-4c25-b80f-db7be1418b9e"
+       _add_nvmet_subsys_to_port "${port}" "blktests-subsystem-1"
+
+       nvme connect -t loop -n blktests-subsystem-1
+
+       local nvmedev
+       nvmedev="$(_find_nvme_loop_dev)"
+
+       udevadm settle
+
+       echo 1 > "/sys/class/nvme/${nvmedev}/reset_controller"
+
+       nvme disconnect -d "${nvmedev}"
+       _remove_nvmet_subsystem_from_port "${port}" "blktests-subsystem-1"
+       _remove_nvmet_port "${port}"
+
+       _remove_nvmet_subsystem "blktests-subsystem-1"
+       losetup -d "$loop_dev"
+       rm "$TMPDIR/img"
+
+       post
+
+       echo "Test complete"
+}

In this way, we can move generic pre and post to the nvme/lib so that
all other tests can also use that?
