perf script: Fix format regression due to libtraceevent merge
Consider the commands:
perf record -e sched:sched_switch -fo /tmp/perf.data -a -- sleep 1
perf script -i /tmp/perf.data
In v3.4 the output has the form (lines wrapped here)
perf 29214 [005] 821043.582596: sched_switch:
prev_comm=perf prev_pid=29214 prev_prio=120
prev_state=S ==> next_comm=swapper/5 next_pid=0 next_prio=120
In 3.5 that same line has become:
perf 29214 [005] 821043.582596: sched_switch:
<...>-29214 [005] 0.000000000: sched_switch:
prev_comm=perf prev_pid=29214 prev_prio=120
prev_state=S ==> next_comm=swapper/5 next_pid=0 next_prio=120
Note the duplicates in the output -- pid, cpu, event name. With
this patch the v3.4 output is restored:
perf 29214 [005] 821043.582596: sched_switch:
prev_comm=perf prev_pid=29214 prev_prio=120
prev_state=S ==> next_comm=swapper/5 next_pid=0 next_prio=120
v3:
Remove that pesky newline too. Output now matches v3.4 (pre-libtracevent).
v2:
Change print_trace_event function local to perf per Steve's comments.
