Every time a scsi bus/port is scanned and a new block device is detected,
we want to call device_probe() as it will give us a chance to run
additional post-processings for some purposes.

In particular, support for creating partitions on a device will be added.

Isn't device_unbind() releasing all resources? What is missing?

Best regards
