This is v2 of [1], with a number of cleanups added first based on Christoph's feedback, making the actual constness patch much smaller and cleaner. I don't know who actually maintains relay, it's not in MAINTAINERS - Cc'd Andrew just in case. I'd think it would be simplest to queue patches 5-9 via whichever tree the relay patches get merged. They're all one-liners so neglible conflict potential. BR, Jani.
