People have been talking about more/more comprehensive power tracepoints
for a while, and I think that's a valid goal, if its really a rename I'm
sure you can work it out.

That said, I really didn't read this discussion much, but your stance
seems to be that any tracepoint you use must stay valid, and I object to
that.

What will do you do when we include a new scheduling policy and all the
scheduler tracepoints need to change? (yes that's really going to
happen)

I'm not going to carry double tracepoints, and I'm not going to not
merge that policy.
