- * Devices *can* be used before status is set to DRIVER_OK.
- * The original plan was that they would never do this: they
- * would always finish setting up their status bits before
- * actually touching the virtqueues. In practice, we allowed
- * them to, and they do (eg. the disk probes for partition
- * tables as part of initialization).
- *
- * If we see this, we start the device: once it's running, we
- * expect the device to catch all the notifications.
