perf bench: Modify bench/bench-messaging.c to adopt unified output formatting
This patch modifies bench/bench-messaging.c to adopt unified output formatting: --format option. Usage example: % ./perf bench sched messaging # with no style specify (20 sender and receiver processes per group) (10 groups == 400 processes run) Total time:1.431 sec % ./perf bench --format=simple sched messaging # specified simple 1.431 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: <1257808802-9420-4-git-send-email-mitake@dcl.info.waseda.ac.jp> Signed-off-by: Ingo Molnar <mingo@elte.hu>
