What's the ballpack performance goal for e.g. post 2.6.12 kernel history
which is about 85k commits, 3800 authors, 24k files?

* Who contributed the most code that needed the many fix-ups on top?

* Which part of the codebase had the most commits that had "oops, screwed
  up, I am fixing this but this is a tricky code" fixes?
