hum, could you please add some info about testing those changes?
(or even some global into 0/.. patch)

this is working for me on python2:

	[root@...va perf]# perf script rec check-perf-trace
	^C
	[root@...va perf]# perf script   -s scripts/python/check-perf-trace.py
	trace_begin

	unhandled events:


	event                                          count

	----------------------------------------  -----------

	raw_syscalls__sys_enter                      3509879


but fails for python3:

	[root@...-x3650m4-01-vm-04 perf]# perf script rec check-perf-trace
	^C[ perf record: Woken up 0 times to write data ]
	Warning:
	1 out of order events recorded.
	[ perf record: Captured and wrote 43.132 MB perf.data (490171 samples) ]

	[root@...-x3650m4-01-vm-04 perf]# perf script   -s scripts/python/check-perf-trace.py
	Traceback (most recent call last):
	  File "scripts/python/check-perf-trace.py", line 18, in <module>
	    from perf_trace_context import *
	ModuleNotFoundError: No module named 'perf_trace_context'
	Error running python script scripts/python/check-perf-trace.py

I did not test with rpm, just did 'make install' for perf

thanks,
jirka
