You need to mention here what these tracers are and which bits of
event's information they need in their setup_aux(). Right now I can look
it up in this patchset, but when this code gets merged it will make it
easier to understand why this change was made.

Now, I understand that you're interested in event::attr in your
setup_aux(), I have more comments on that in that other patch. :)
