    I've been posting recently. This one adds:
       - slave_attach() and slave_detach()
       - code clean up looking for a problem **
       - more debug code allowing scanning cmd sequence to
         be seen in the log (when opts=1)
    
    ** after several (never the first) sequences of modprobe/rmmod
    on scsi_debug there is either:
       - an oops during modprobe when driverfs tries to create a
         directory
       - or a WARN_ON() at drivers/base/bus.c:277 during rmmod
    [examples attached]
    
    I'm not sure whether the problem is in scsi_debug, the
    scsi mid level or in the driverfs code. Grepping indicates
    that not many people currently utilize per driver parameters
    with driverfs (i.e. driver_create_file() and
    driver_remove_file()).
