perf stat: Align scaled output of cpu-clock
The output of cpu-clock event is controlled in nsec_printout(), but its alignment was broken: Performance counter stats for 'sleep 1': 6,038,774 instructions # 0.00 insns per cycle 180 faults # 0.007 K/sec [99.95%] 1,282,201 branches # 0.053 M/sec [99.84%] 24126.221811 cpu-clock [99.62%] 24121.689540 task-clock # 24.098 CPUs utilized [99.52%] 1.001001017 seconds time elapsed This patch fixes this: Performance counter stats for 'sleep 1': 13,540,843 instructions # 0.00 insns per cycle 180 faults # 0.007 K/sec [99.94%] 2,875,386 branches # 0.119 M/sec [99.82%] 24144.221137 cpu-clock [99.61%] 24133.515366 task-clock # 24.109 CPUs utilized [99.52%] 1.001020946 seconds time elapsed Cc: Ingo Molnar <mingo@elte.hu> Cc: Namhyung Kim <namhyung@gmail.com> Cc: Paul Mackerras <paulus@samba.org> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Link: http://lkml.kernel.org/r/1328514285-26232-2-git-send-email-namhyung.kim@lge.com Signed-off-by: Namhyung Kim <namhyung.kim@lge.com> Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
