名称描述
rcu_sched_clock_irqThis function is invoked from each scheduling-clock interrupt,* and checks to see if this CPU is in a non-context-switch quiescent* state, for example, user mode or idle loop. It also schedules RCU* core processing
rcu_corePerform RCU core processing work for the current CPU.
rcu_cpu_kthreadPer-CPU kernel thread that invokes RCU callbacks. This replaces* the RCU softirq used in configurations of RCU that do not support RCU* priority boosting.
rcu_note_context_switchNote a PREEMPT=n context switch. The caller must have disabled interrupts.
