rcu: Break more call_rcu() deadlock involving scheduler and perf Commit 96d3fd0d315a9 (rcu: Break call_rcu() deadlock involving scheduler and perf) covered the case where __call_rcu_nocb_enqueue() needs to wake the rcuo kthread due to the queue being initially empty, but did not do anything for the case where the queue was overflowing. This commit therefore also defers wakeup for the overflow case. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
