Now that the rcu_data structure contains ->gp_seq_needed, create an rcu_accelerate_cbs_unlocked() helper function that locklessly checks to see if new callbacks' required grace period has already been requested. If so, update the callback list locally and again locklessly. (Though interrupts must be and are disabled to avoid racing with conflicting updates in interrupt handlers.) Otherwise, call rcu_accelerate_cbs() as before. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> |
