Or:
	- someone gets a GPL only license file added to the openib code
	  base in the linux kernel, by slipping it in through another
	  path to Linus.

Odds are, that's going to happen before the above does :)

Remember, the openib code uses functions that are marked
EXPORT_SYMBOL_GPL() and if _anyone_ violates those markings by trying to
ship a openib derivative work with a non-gpl license, they will be hearing
from some lawyers very quickly.

And as more and more "feature xyz" in the kernel are being marked GPL
only, it's only a matter of time...
