10   Fast scanning for modern (SCSI-3) devices by sending a REPORT LUN command.
11   Scan the resulting list of LUNs by calling scsi_probe_and_add_lun.

14   If BLINK_REPORTLUN2 is set, scan a target that supports more than 8
15   LUNs even if it's older than SCSI-3.
16   If BLIST_NOREPORTLUN is set, return 1 always.
17   If BLIST_NOLUN is set, return 0 always.
18   If starget-&gt;no_report_luns is set, return 1 always.
