Hey, it was eventually noticed :-)

Would be nice if linux-next posted a daily before/after commit 
bloatometer stats top list - unfortunately this would be pretty 
time consuming to acquire due to the many rebasing Git trees. 

With a proper Git workflow enforced it would be a few dozen 
kernel builds per release, easily done on a fast enough box.

Thanks,
