Thank you very much for the hint -- this is an oversight on my behalf. I wanted the test kernel code to be licensed in a dual BSD/GPLv2 style. As this is just a test module to demonstrate the appropriateness of the offered patch, I hope you can still live with it until a potential new submission is provided. Though, if you insist I can resubmit the test module with the dual BSD/GPLv2 clause.
