Subject: ring-buffer: Kernel threads cpu utilization.

rb_producer and rb_comsumer, kernel thread uses lot of CPU (~100%)
bandwidth every 10s.

bisection results commit:
[5092dbc96f3acdac5433b27c06860352dc6d23b9] ring-buffer: add benchmark and tester
I have read commit logs:
git log -r 5092dbc96f3acdac5433b27c06860352dc6d23b9

Is it correct behavior for these thread to consume this much cpu
bandwidth even if someone selects rb benchmarks config options?

thanks
-tej
