This selftest patch I had to apply manually due to conflicts.
I've also removed the noisy printk before pushing.

Thanks! I had the printk there to verify the code was actually
being run, but forgot to remove it before submitting.

I verified that I saw the spam before removing it.

Great.

The patch 1 looks great. Thanks a lot for the fix.
