			   struct scsi_mode_data * data, struct scsi_sense_hdr * sshdr);

ARGUMENTS
       sdev
	   SCSI device to be queried

       dbd
	   set if mode sense will allow block descriptors to be returned

       modepage

       data
	   returns a structure abstracting the mode header data

       sshdr
	   place to put sense data (or NULL if no sense to be collected). must be SCSI_SENSE_BUFFERSIZE big.
