+ * sg_scsi_ioctl  --  handle deprecated SCSI_IOCTL_SEND_COMMAND ioctl
+ * @file:	file this ioctl operates on (optional)
+ * @q:		request queue to send scsi commands down
+ * @disk:	gendisk to operate on (option)
+ * @sic:	userspace structure describing the command to perform
+ *
+ * Send down the scsi command described by @sic to the device below
+ * the request queue @q.  If @file is non-NULL it's used to perform
+ * fine-grained permission checks that allow users to send down
+ * non-destructive SCSI commands.  If the caller has a struct gendisk
+ * available it should be passed in as @disk to allow the low level
+ * driver to use the information contained in it.  A non-NULL @disk
+ * is only allowed if the caller knows that the low level driver doesn't
+ * need it (e.g. in the scsi subsystem).
+ *
+ * Notes:
+ *   -  This interface is deprecated - users should use the SG_IO
+ *      interface instead, as this is a more flexible approach to
+ *      performing SCSI commands on a device.
+ *   -  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
+ *   -  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.

- * 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.
