This patch (as1507) adds a skip_vpd_pages flag to struct scsi_device and a no_report_luns flag to struct scsi_target. The first is used to control whether sd will look at VPD pages for information on block provisioning, limits, and characteristics. The second prevents scsi_report_lun_scan() from issuing a REPORT LUNS command. The patch also modifies usb-storage to set the new flag bits for all USB devices and targets, and to stop adjusting the scsi_level value. Historically we have seen that USB mass-storage devices often don't support VPD pages or REPORT LUNS properly. Until now we have avoided these things by setting the scsi_level to SCSI_2 for all USB devices. But this has the side effect of storing the LUN bits into the second byte of each CDB, and now we have a report of a device which doesn't like that. The best solution is to stop abusing scsi_level and instead have separate flags for VPD pages and REPORT LUNS.
