- * Encoding the size of the parameter structure in the ioctl request
- * is useful for catching programs compiled with old versions
- * and to avoid overwriting user space outside the user buffer area.
- * The highest 2 bits are reserved for indicating the ``access mode''.
- * NOTE: This limits the max parameter size to 16kB -1 !

- * The following is for compatibility across the various Linux

- * a type field.  De facto, however, the top 8 bits of the lower 16
- * bits are indeed used as a type field, so we might just as well make
- * this explicit here.  Please be sure to use the decoding macros
