> to be provided with a function pointer (callback). This patch adds
> 3 static counters and 3 static functions that simply increment these

Long term, it's going to run into -Wunused-function. Suggest adding a
disclaimer pointing out this limitation :-)
Otherwize (for want of any beter idea :-), ok.
