McKenney <paulmck@xxxxxxxxxxxxx> CommitDate: Thu, 8 Nov 2018 21:43:20 -0800 sparc/oprofile: Convert timer_stop() to use synchronize_rcu() Now that synchronize_rcu() waits for preempt-disable regions of code in addition to explicitly marked RCU read-side critical sections, synchronize_rcu() can be used in place of synchronize_sched(). This commit therefore makes that change. Signed-off-by: Paul E. McKenney <paulmck@xxxxxxxxxxxxx> Cc: Robert Richter <rric@xxxxxxxxxx> Cc: "David S.
