[PATCH tip/core/rcu 05/12] rcu: provide rcu_batches_completed_sched() for TINY_RCU

From: Paul E. McKenney
Date: Wed Jan 07 2015 - 13:23:31 EST


From: "Paul E. McKenney" <paulmck@xxxxxxxxxxxxxxxxxx>

A bug in rcutorture has caused it to ignore completed batches.
In preparation for fixing that bug, this commit provides TINY_RCU with
the required rcu_batches_completed_sched().
