dl_period = global_rt_period()

dl_runtime = global_rt_runtime()

2522

If global_rt_runtime() != Single value that denotes runtime == period, ie unlimited time. Then new_bw = to_ratio(global_rt_period(), global_rt_runtime())

_read_lock_sched() - mark the beginning of a RCU-sched critical section* This is equivalent of rcu_read_lock(), but disables preemption.* Read-side critical sections can also be introduced by anything else

dl_b = dl_bw_of(cpu)
