Subject: Re: [PATCH v1 4/6] perf auxtrace: Iterate all AUX events when finish reading

Just a heads up. Arnaldo added this to tmp.perf-tools-next and it
caused the intel-pt tests to start failing:
```
$ perf test 118 -v
118: Miscellaneous Intel PT testing:
--- start ---
test child forked, pid 148999
--- Test system-wide sideband ---
Checking for CPU-wide recording on CPU 0
OK
Checking for CPU-wide recording on CPU 1
OK
Linux
Failed to enable event (idx=0): -22
Failed to record MMAP events on CPU 1 when tracing CPU 0
...
```
It's likely Adrian's comments already address this but you may also
want to double check this test is passing with v2.

Thanks,
Ian
