That would clash again, as in my tree I have it as:
static int perf_session__deliver_event(struct ordered_events *oe,
struct ordered_event *event,
struct perf_sample *sample)
return machines__deliver_event(oe->machines, oe->evlist, event->event,
sample, oe->tool, event->file_offset);
Which is a misnomer really, as by now it has nothing to do with a
perf_session, its all about ordered_event to a ordered_events.
We'll get that sorted out eventually. Sorry for the flux, but its trying
to get it to a better, more fine grained state.

That should match whatever name is used for the kernel facility it will
handle.... both auxtrace and hwtrace looks too ambiguous...
