perf bench: Improve sched-pipe.c with more comfortable output
This patch improves sched-pipe.c with more comfortable output. Change points are comment style description and formatting numerical values and its units. Example: | % ./perf bench sched pipe | # Running sched/pipe benchmark... | # Extecuted 1000000 pipe operations between two tasks | | Total time:5.822 [sec] | | 5.822553 usecs/op | 171745 ops/sec Signed-off-by: Hitoshi Mitake <mitake@dcl.info.waseda.ac.jp> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> LKML-Reference: <1257865442-20252-3-git-send-email-mitake@dcl.info.waseda.ac.jp> Signed-off-by: Ingo Molnar <mingo@elte.hu>
