rcu: Add leaf-node macros This commit adds rcu_first_leaf_node() that returns a pointer to the first leaf rcu_node structure in the specified RCU flavor and an rcu_is_leaf_node() that returns true iff the specified rcu_node structure is a leaf. This commit also uses these macros where appropriate. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Tested-by: Nicholas Piggin <npiggin@gmail.com>
