[PATCH tip/core/rcu 41/41] rcutorture/formal: Replace synchronize_sched() with synchronize_rcu()

From: Paul E. McKenney
Date: Sun Nov 11 2018 - 14:44:52 EST


Now that synchronize_rcu() waits for preempt-disable regions of code
as well as RCU read-side critical sections, synchronize_sched() can be
replaced by synchronize_rcu(). This commit therefore makes this change,
even though it is but a comment.
