I guess it would look pretty terrible, but given it's debugfs very
unlikely.

I didn't pre-align this with the other AMD guys.  It was just something
I noticed that has annoyed me as I look at bugs that I'm looking at and
since it's not sensitive content figured public review is fine for it.

That's why I left them on To: line.  But yes as you say if others don't like
it reverts are cheap and it's better to have enough time for good testing
coverage.
