Something like scsi_add_device/scsi_remove_device as described above would
be "very" helpful for the IEEE-1394 SBP-2 hot-plugging support. The "add"
part is quite simple, since it ultimately just calls scan_scsis. The
"remove" part is a bit more difficult, unless the user has unmounted the
disk before hot-unplugging it, because of the attached usage count. Douglas
has mentioned that the usage count could be made more accurate to help with
this... ;-)
