On second thought, I'm not so sure this would work the way I want.
scsi_device_get() ends up being called for all sorts of extra things
unrelated to device opens. For instance, scsi_probe_and_add_lun()
calls it whenever a new LUN is discovered.
True.
Would it be acceptable to add a similar pair of callbacks to the host
template, invoked by the upper-level driver's open and release
routines?
This would actually be nice for that sbp2 thing which I mentioned as well.
