rcu/nocb: Avoid synchronous wakeup in __call_rcu_nocb_wake() When callbacks are in full flow, the common case is waiting for a grace period, and this grace period will normally take a few jiffies to complete. It therefore isn't all that helpful for __call_rcu_nocb_wake() to do a synchronous wakeup in this case. This commit therefore turns this into a timer-based deferred wakeup of the no-CBs grace-period kthread. Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com>
