Ok. To be more precise, this patch has two properties that other patches
of the "make later patches easier to apply" class tend not to:
* it introduces a significant functional change (adding tracepoints)
* it would have been very easy to skip
Have fun, and sorry for not explaining my reasoning before.
Ciao,
