As the thread suggested, this can benefit us more than it benefits
them, because it may let us see more into the blobs.

The marker_probe_*register calls are already EXPORT_SYMBOL_GPL'd, so
that covers your "tomorrow" case. NACK that all you like when/if
someone proposes changing that.

(In a way, it would be a nice problem to have. At this moment, there
are still no markers actually committed within -mm nor -linus.)
