Also, just to make sure this is resolved properly, I'm NAK-ing the current
scheduler bits in this series:

NAKed-by: Ingo Molnar <mingo@xxxxxxxxxx>

until all of pjt's API design concerns are resolved. This is conceptual, it is not
a 'we can fix it later' detail.

Tejun, please keep me Cc:-ed to future versions of this series so that I can lift
the NAK if things get resolved.

Thanks,

Ingo
