SCSI was designed with this in mind. The add/remove-single-device API works
before a dev node exists. It expects four numeric parameters
(host,channel,pun and lun), and will do the inquiry and attach the correct
SCSI upper layer drivers.
Thus I still contend there's nothing you can get out of in-kernel exposure of
these APIs that you couldn't do from a hotplug event.
I agree that we don't have the correct SCSI hot plugging in place today, but
exposing in-kernel add/remove won't help with that.
