could you please split this patch into logically separated changes, like:
- adding PERF_RECORD_NAMESPACES event with perf_event__process_namespaces
machinery
- synthesize support (perf_event__synthesize_namespaces) for record
- script print support
- perf_event__fprintf print support
or any other split that'd make sense, it's too many changes for one patch now
thanks,
jirka
