So you agree that I can add debugging printk's only for my own use?
I can claim that I only use them downstream and you can't force me
to carry local changes?

If not, what is your criteria for accepting debugging printk's? Whose
can be accepted and whose can't?

Please be specific, and ideally make it a formal doc in netdev-FAQ.txt.

Thanks!
