+# ioctl command encoding: 32 bits total, command in lower 16 bits,
+#  size of the parameter structure in the lower 14 bits of the
+#  upper 16 bits.
+#  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
+#  platforms.  The generic ioctl numbering scheme doesn't really enforce
+#  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
+#  below from now on.
