To my astonishment, after tracing some things in the driver, I see that the
devices aren't created UNTIL they are opened!  This is not the behavior I
expected, to say the least.

I'm having other problems with target mode, and with the sample program
provided:

First, although  camcontrol devlist -v  does show a target on the bus,
the other side of the FC loop isn't seeing  it.  Second, when I send it
the DEL signal, it doesn't shut down.  It hangs on an IOCTL (TARGIOCDISABLE)
and I have traced the stoppage (via printf()s in the driver, UGH!) to
scsi_target.c: abort_all_pending(), which waits (presumably) on what it
has aborted.  Now I'm trying to figure out what that was.

As before, any help will be welcome.
