perf evlist: Reset SIGTERM handler in workload child process
Jiri reported hanging perf tests on latest acme's perf/core and bisected
it to 87f303a9f:
[jolsa@krava2 perf]$ cat /proc/sys/kernel/perf_event_paranoid
1
[jolsa@krava2 perf]$ ./perf record -C 0 kill
Error:
You may not have permission to collect %sstats.
Consider tweaking /proc/sys/kernel/perf_event_paranoid:
-1 - Not paranoid at all
0 - Disallow raw tracepoint access for unpriv
1 - Disallow cpu events for unpriv
2 - Disallow kernel profiling for unpriv
Need to let default handling kickin for workload process.
