  *          needs to be created so the most efficient IOCtl data buffering method can be
  *          used.
+ *
+ * @remark  On Linux (at least), things are not as grim as portrayed above.  The IOCtl
+ *          numbering system is pure convention designed in order to simplify error checking.
+ *          The numbers only have meaning to the driver which implements the IOCtl, and are
+ *          completely ignored by the system.  In fact, the oldest IOCtls still in use today
+ *          predate the current numbering system, and several of the ones implemented since
+ *          then implement it wrongly.  See 'man ioctl_list' for more information.
