It might be easier to manage the TRACE_EVENT() reshaping (removal of semicolumn,
tp_assign, etc) I am preparing if, at this stage, we merge most of the
include/trace/event patches through a single tree (the tracing tree). Otherwise
we might end up with more commit cross-dependencies between the trees, and
increase the risk of conflicts.

Thanks,
