Name:Is the current CPU in an extended quiescent state?* No ordering, as we are sampling CPU-local information.
Proto:bool rcu_dynticks_curr_cpu_in_eqs(void)
Type:bool
Parameter:Nothing
299 | rdp = this_cpu_ptr( & rcu_data) |
301 | Return Not (atomic_read( & Even value for idle, else odd. ) & RCU_DYNTICK_CTRL_CTR) |
Name | Describe |
---|---|
rcu_nmi_exit_common | If 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_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 |
rcu_is_watching | _is_watching - see if RCU thinks that the current CPU is not idle* Return true if RCU is watching the running CPU, which means that this* CPU can safely enter RCU read-side critical sections |
