Please make sure that SCSI_UNLIMITED_CMD_PER_LUN has type "short"
instead of "int". Otherwise comparisons like "shost->cmd_per_lun !=
SCSI_UNLIMITED_CMD_PER_LUN" will trigger a conversion from "short" to
"int" for "shost->cmd_per_lun" before the actual conversion happens. I
don't think that's what we want ...
Thanks,
Bart.
