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. If starget->no_report_luns is set, return 1 always. 0 scan completed (or no memory, so further scanning is futile) 1 could not scan with REPORT LUN AUTHORS
