It adds bloat, I agree. I haven't run any tests, but I can't imagine it
has a runtime impact. Your suggestions feel a lot like the existing code
to me, which was not easy to digest.

My goal was to make the code easier to understand, and removing the
black magic was just part of that. To me it's the most obvious way to
understand how the semaphores work, though I could be in the minority.
It also provides an easy way to put per ring debug, add new rings, and
disable/enable semaphores for a given ring (your idea, which I really
like). I don't feel strongly enough about it to argue further than that.
I'm cool with letting the patches die if others don't agree.
