+ * This macro waits concurrently for multiple types of RCU grace periods.
+ * For example, synchronize_rcu_mult(call_rcu, call_rcu_tasks) would wait
+ * on concurrent RCU and RCU-tasks grace periods.  Waiting on a give SRCU
  * domain requires you to write a wrapper function for that SRCU domain's
  * call_srcu() function, supplying the corresponding srcu_struct.

- * If Tiny RCU, tell _wait_rcu_gp() not to bother waiting for RCU
- * or RCU-sched, given that anywhere synchronize_rcu_mult() can be called
- * is automatically a grace period.
