 /*
- * This interface is deprecated - users should use the scsi generic (sg)
- * interface instead, as this is a more flexible approach to performing
- * generic SCSI commands on a device.
- *
- * The structure that we are passed should look like:
- *
- * struct sdata {
- *  unsigned int inlen;      [i] Length of data to be written to device 
- *  unsigned int outlen;     [i] Length of data to be read from device 
- *  unsigned char cmd[x];    [i] SCSI command (6 <= x <= 12).
- *                           [o] Data read from device starts here.
- *                           [o] On error, sense buffer starts here.
- *  unsigned char wdata[y];  [i] Data written to device starts here.
- * };
- * Notes:
- *   -  The SCSI command length is determined by examining the 1st byte
- *      of the given command. There is no way to override this.
- *   -  Data transfers are limited to PAGE_SIZE (4K on i386, 8K on alpha).
- *   -  The length (x + y) must be at least OMAX_SB_LEN bytes long to
- *      accommodate the sense buffer when an error occurs.
- *      The sense buffer is truncated to OMAX_SB_LEN (16) bytes so that
- *      old code will not be surprised.
- *   -  If a Unix error occurs (e.g. ENOMEM) then the user will receive
- *      a negative return and the Unix error code in 'errno'. 
- *      If the SCSI command succeeds then 0 is returned.
- *      Positive numbers returned are the compacted SCSI error codes (4 
- *      bytes in one int) where the lowest byte is the SCSI status.
- *      See the drivers/scsi/scsi.h file for more information on this.
- *
