Similar to <function>EXPORT_SYMBOL()</function> except that the
symbols exported by <function>EXPORT_SYMBOL_GPL()</function> can
only be seen by modules with a
<function>MODULE_LICENSE()</function> that specifies a GPL
compatible license. It implies that the function is considered
an internal implementation issue, and not really an interface.
"not really an interface"....
Should it really be EXPORT_SYMBOL_GPL?
