NAME
       scsi_report_lun_scan - Scan using SCSI REPORT LUN results

SYNOPSIS
       int scsi_report_lun_scan(struct scsi_target * starget, int bflags, int rescan);

ARGUMENTS
       starget
	   which target

       bflags
	   Zero or a mix of BLIST_NOLUN, BLIST_REPORTLUN2, or BLIST_NOREPORTLUN

       rescan
	   nonzero if we can skip code only needed on first scan

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

       If BLINK_REPORTLUN2 is set, scan a target that supports more than 8 LUNs even if it's older than SCSI-3. If BLIST_NOREPORTLUN is set,
       return 1 always. If BLIST_NOLUN is set, return 0 always.

0
       scan completed (or no memory, so further scanning is futile)

1
       could not scan with REPORT LUN
