perf bench: Add sched-pipe.c: Benchmark for pipe() system call
This patch adds bench/sched-pipe.c.
bench/sched-pipe.c is a benchmark program
to measure performance of pipe() system call.
This benchmark is based on pipe-test-1m.c by Ingo Molnar:
http://people.redhat.com/mingo/cfs-scheduler/tools/pipe-test-1m.c
Example of use:
% perf bench sched pipe
(executing 1000000 pipe operations between two tasks)
Total time:4.499 sec
4.499179 usecs/op
222262 ops/sec
% perf bench sched pipe -s -l 1000
0.015
