Daniel, I can't hold a candle to your abilities and I respect your
talents and Linux contributions but what are your motives with this
flame?

I think injecting such uninformed/speculative negativity is an awkward
and misplaced distraction.  If you look at the archives there was a
flurry of (sometimes heated) discussion between Con and Ingo.  They
seemed to bury the hatchet and get back to critical discussion and
analysis of CFS et al.

Maybe I'm naive and/or missing something but Ingo doesn't seem to be
the glory whore type.  He clearly has a strong interest in improving
Linux and brings his unique abilities to bear on very complex Linux
subsystems.  We should be grateful that he has elected to dedicate so
much time to improving the CPU scheduler.  Ingo has injected new
momentum and innovation, yes he leveraged Con's work.  But to be
clear: he did so in an open forum and has engaged Con and the rest of
LKML the entire time.
