ok, while this is a test patch of yours, lets make one thing sure: all
things hook-alike instrumentation _MUST_ and will stay stay GPL
exported. It's all very internal, and there will be no automatic,
programmable interface stability guarantees for any of the markers that
kabi crap could come and shackle the kernel with ... (it will all be
stable to SystemTap of course - but SystemTap is a kernel-internal
entity in that regard)
