Elsewhere in this series you use 'pers' to shorten things; it reads a
bit odd to me because 'pers' is the Dutch word for press (both meanings
transfer) but that is just something I'll have to live with isn't it ;-)
As for tracepoint, it seems common to shorten that to tp; which always
reminds me of toilet paper, but I suppose more people suffer from that.
Yielding: perf_add_pers_tp()
which I read as adding pressed toilet paper.. a well :-)
