thanks for the review comments. I really think we should do something about the trunk_nr:

#define LOGPTRUNK(trunk, cat, level, fmt, args...) \
LOGP(cat, level, "trunk:%u " fmt, \  <============ %u (!)
     trunk ? trunk->trunk_nr : 0, \
     ## args)

PS4, Line 138: 	if (endp->trunk->stats.common) {
> can this be null? does it make sense that it's null?
There is a problem with the unit-tests. They do not allocate the trunks really, they just create a variable with some endpoints in it, which are also variables. If I don't check, it crashes.

Done

I also don't understand why, I should check this back and refactor it too (if possible) - but it would be easier if we could do this in a follow up patch.
