Name:synchronize_rcu_expedited - Brute-force RCU grace period* Wait for an RCU grace period, but expedite it
Proto:void synchronize_rcu_expedited(void)
Type:void
Parameter:Nothing
793 | boottime = The rcu_scheduler_active variable is initialized to the value* RCU_SCHEDULER_INACTIVE and transitions RCU_SCHEDULER_INIT just before the* first task is spawned == RCU_SCHEDULER_INIT |
798 | RCU_LOCKDEP_WARN(lock_is_held( & rcu_bh_lock_map) || lock_is_held( & rcu_lock_map) || lock_is_held( & rcu_sched_lock_map), "Illegal synchronize_rcu_expedited() in RCU read-side critical section") |
804 | If During early boot, any blocking grace-period wait automatically* implies a grace period Then Return |
815 | If Funnel-lock acquisition for expedited grace periods Then Return |
822 | Else |
