Very nice, applied to tip:perf/bench, thanks!

A (very) small detail about initializers in bench.h:

 - No need to break the line for function prototypes, they are more
   readable in a single line. (even if checkpatch complains about it)

 - We try to align definitions / structure fields vertically, to make it 
   all a bit more readable.

Something like the (untested) cleanup patch below. (Just put it into 
your next batch of commits.)

Thanks,

	Ingo
