When 'perf top' is run, one can't easily find a difference
between -z option and normal output.
So I added a visual cue to know whether it is the zeroing or not.
Output is as below.
Before:
$ perf top
Samples: 61K of event 'cycles', Event count (approx.): 3908136933
Overhead Shared Object Symbol
1.42% firefox [.] 0x0000000000011e76
1.32% libpthread-2.17.so [.] pthread_mutex_lock
If you press key 'z' or run with zero option like '$ perf top --zero', it is as below.
After:
Samples: 61K of event 'cycles', Event count (approx.): 3908136933 [z]
Overhead Shared Object Symbol
1.42% firefox [.] 0x0000000000011e76
1.32% libpthread-2.17.so [.] pthread_mutex_lock
