rcu: Extend expedited funnel locking to rcu_data structure The strictly rcu_node based funnel-locking scheme works well in many cases, but systems with CONFIG_RCU_FANOUT_LEAF=64 won't necessarily get all that much concurrency. This commit therefore extends the funnel locking into the per-CPU rcu_data structure, providing concurrency equal to the number of CPUs. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
