Hi Adrian,
I have just resubmitted these changes as a new patch set, which I believe
should address most of your concerns. Please review the new patch set
instead of continuing with this one.
https://lkml.org/lkml/2016/4/28/75
Thanks,
Chris

It is intended to demonstrate how it accounts separately
for the two ways to reach the "inc_x_loop" function(via "a" and "b").
Recursive common table expressions can be used as well to get cumulative
time spent in a function as well, but that is beyond the scope of this
