When i use perf to trace the sched_wakeup_new tracepoint, there is
a bug that output the same event repetitiously.
It can be reproduced by :
#./test_fork
parent pid : 1059
child pid : 1060
#perf record -e sched:sched_wakeup_new -p 1060
test_fork is
When i use perf to trace the sched_wakeup_new tracepoint, there is
a bug that output the same event repetitiously.
It can be reproduced by :
#./test_fork
parent pid : 1059
child pid : 1060
#perf record -e sched:sched_wakeup_new -p 1060
test_fork is
