The probe_container mechanism requires a target id to be present,

As we're now allocating internal commands the target id of the

A more elegant solution is probably to introduce private data per SCSI
command and to set the .cmd_size member in the SCSI host template. I'd
like to get rid of the host_scribble field because it makes the SCSI
command data structure larger than necessary for SCSI LLDs that don't
use 'host_scribble'.
Ah. Good idea, both with using the .cmd_size and removing the
host_scribble field.
Cheers,
