I had a glance at tools/perf/design.txt the other day, and it
appears to be pretty far out of date.
Is design.txt a document that you want to keep the current way for
historical reasons [and the up-to-date documentation placed somewhere
else], or one that should be maintained?
I'm wondering if some/all of this documentation should move into
include/linux/perf_event.h

Its the ineffiteble fate of everything Documentation/ to be out-dated.
But yeah, that file will be woefully inaccurate by now.
Yeah, I think making perf_event.h more explanatory would be good. But I
don't think we want to go overboard there either, if comments get too
large and unwieldy they tend to bitrot just as hard as Documentation/

Maybe the file should at least move to the normal burial ground for docs, Documentation, rather than where it is today tools/perf. Perhaps there it would be easier for people to find and correct.
