NameDescribe
rcu_eqs_enterEnter an RCU extended quiescent state, which can be either the* idle loop or adaptive-tickless usermode execution.* We crowbar the ->dynticks_nmi_nesting field to zero to allow for* the possibility of usermode upcalls having messed up our count
rcu_nmi_exit_commonIf we are returning from the outermost NMI handler that interrupted an* RCU-idle period, update rdp->dynticks and rdp->dynticks_nmi_nesting* to let the RCU grace-period handling know that the CPU is back to* being RCU-idle
rcu_eqs_exitExit an RCU extended quiescent state, which can be either the* idle loop or adaptive-tickless usermode execution.* We crowbar the ->dynticks_nmi_nesting field to DYNTICK_IRQ_NONIDLE to* allow for the possibility of usermode upcalls messing up our count of
rcu_nmi_enter_common_nmi_enter_common - inform RCU of entry to NMI context*@irq: Is this call from rcu_irq_enter?* If the CPU was idle from RCU's viewpoint, update rdp->dynticks and* rdp->dynticks_nmi_nesting to let the RCU grace-period handling know* that the CPU is active
