Using DTrace on Kernel Extensions in OS X

I am currently working with the ZFS port to OS X which is a
kext.  I had heard that you cannot use DTrace on kexts in OS
X at the moment.  Does anyone know why?

	The dog ate that code.

	Kexts are SO nineties, we think they're going away.

	The Brady-Barr kext control act of 2007 required us not to
ship that  
code by law.

	It's a GPL v4 licensing issue.

	Or, possibly we just didn't get that functionality
implemented yet .
