* synchronize_rcu_mult - Wait concurrently for multiple grace periods
* @...: List of call_rcu() functions for the flavors to wait on.
* @...: List of call_rcu() functions for different grace periods to wait on
*
* This macro waits concurrently for multiple flavors of RCU grace periods.
* For example, synchronize_rcu_mult(call_rcu, call_rcu_sched) would wait
* on concurrent RCU and RCU-sched grace periods. Waiting on a give SRCU
* 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.
* If Tiny RCU, tell _wait_rcu_gp() does not bother waiting for RCU,
