    Show the SCSI CDB for pending SCSI commands in
    /sys/kernel/debug/block/*/mq/*/dispatch and */rq_list. An example
    of how SCSI commands are displayed by this code:
    
    ffff8801703245c0 {.op=READ, .cmd_flags=META PRIO, .rq_flags=DONTPREP IO_STAT STATS, .tag=14, .internal_tag=-1, .cmd=Read(10) 28 00 2a 81 1b 30 00 00 08 00}
