Subject[PATCH v1 4/4] perf intel-pt, intel-bts: Suppress useless AUX records by default
Date
This makes use of the shiny new attr::suppress_aux that suppresses the
AUX records that don't carry any 'interesting' information for the
decoders, that is PERF_RECORD_AUX[flag==OVERWRITE], which just stack up
in the DATA buffer for no good reason.
