I know I used ftrace as an example, but a more appropriate example
would be the sched knobs, as this is more about rcu scheduling than
anything else.

See:

sched_autogroup_enabled sched_rr_timeslice_ms
sched_child_runs_first sched_rt_period_us
sched_domain/ sched_rt_runtime_us
sched_latency_ns sched_shares_window_ns
sched_migration_cost_ns sched_time_avg_ms
sched_min_granularity_ns sched_tunable_scaling
sched_nr_migrate sched_wakeup_granularity_ns

In particular, the sched_rt_* ones.
