The current code is using a bitmap for sched_busy_hysteresis_enable_cpus tunable. Since the feature is not enabled for any of the CPUs, the default value is printed as "\n". This is very inconvenient for user space applications which tries to write a new value and try to restore the previous value. Like other scheduler tunables, use the bitmask to avoid this issue.
