I'm not really sure what to do about this patch to be honest.

My understanding is that tracepoints are considered as userspace ABI,
but I can't really judge whether your traces are good enough or if it's
something that will bit us some time down the road.

Emma, Daniel, David, any insight?

Thanks,
Maxime
