Re: Executing a scsi command

[MShetty <mranalini.shetty@patni.com>]

Hi,

Does request_queue's queuedata contain the Scsi_Device pointer ?? Saw it
done in scsi_merge.c

      Scsi_Device *SDpnt;
      struct Scsi_Host *SHpnt;

      SDpnt = (Scsi_Device *) q->queuedata;
      SHpnt = SDpnt->host;

Would help if I could get some comment on the above.

Thanks and Regards,
M Shetty
