Work "with" Ingo?  That's turned out well so far.  I'm sure certain 
scheduler people could comment here too on where that gets you.

The kernel I run is "Linux" not "Ingoix".  So I await a comment from Linus 
on this issue.  If it turns out that he's happy with Ingo's work, fine.
It just means I'll have to start maintaining some perf counter related 
patches out of tree for those of us who actually like having control on 
what we're measuring.
