rcu_read_lock_bh	_read_lock_bh() - mark the beginning of an RCU-bh critical section* This is equivalent of rcu_read_lock(), but also disables softirqs
rcu_read_lock_sched	_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
