As was just reported, this breaks things all over the place:
	https://lore.kernel.org/r/219030d8-3408-cc9d-7aec-1fb14ab891ce@roeck-us.net

Note, I also had to add lots of fix-up patches on top of these two that
you missed, so odds are there are other fix-ups that I also missed.

Please go and test this again, and submit ALL patches that are needed
after they pass the proper testing and I will be glad to reconsider them
again.

thanks,
