call_rcu_tasks => rcu_call_tasks ?

The consolidation of RCU, RCU-bh, and RCU-sched would eliminate the
only use of synchronize_rcu_mult(). Should we simply remove it?

All of rcu_barrier, rcu_barrier_bh, rcu_barrier_sched, rcu_barrier_tasks,
and srcu_barrier remain unchanged, correct?

call_srcu => srcu_call ?
And rcu_assign_pointer, rcu_access_pointer(), and rcu_dereference*()
remain unchanged, correct? I wouldn't expect RCU's list API to change,
but if we are going to change something, this would be the time...
On the other hand, the ones you list above are the ones that get used,
hence the ones for which the names are most important. That said...
The following list is a bit out of date, but is not too far off:
Yeah, I know, causing trouble for myself. ;-)
