If nobody objects I'll merge this patch, as it fixes problems, but I
wonder if the best wouldn't be simply not calling
perf_evlist__mmap_consume() till the last event there is in fact
consumed... I.e. as we _really_ consume the events, we remove it from
there.

Instead of consuming the event at perf_tool->sample() time, we would
do it at perf_tool->finished_round(), would that be feasible? Has anyone
tried this?

Hmmm... haven't tried this. Conceptually it should work - at least nothing comes to mind at the moment.


Patch looked ok to me: Reviewed-by: David Ahern <dsahern@xxxxxxxxx>

Jiri should review based on his recent changes for ordered events.
