           Summary: SCSI Generic queueing info result never indicates
                    direct data transfer?
           Product: IO/Storage
           Version: 2.5
    Kernel Version: 2.6.18-2.6.32
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: SCSI
        AssignedTo: linux-scsi@vger.kernel.org
        ReportedBy: mh-linux-kernel@loup.net
        Regression: No


The sg info result never returns a nonzero result despite
SG_FLAG_DIRECT_IO flag and aligned READ_10 and WRITE_10 data buffer.
Is direct io occuring as requested?  If not, why not?  If so, why
doesn't the info value behave as documented in the HOWTO?

I've run both over usb (which I can understand why not direct) and
to SATA drives that normally work fine with O_DIRECT read/write.
