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
