McKenney <paulmck@xxxxxxxxxxxxx> CommitDate: Tue, 27 Nov 2018 09:21:45 -0800 percpu-refcount: Replace call_rcu_sched() with call_rcu() Now that call_rcu()'s callback is not invoked until after all preempt-disable regions of code have completed (in addition to explicitly marked RCU read-side critical sections), call_rcu() can be used in place of call_rcu_sched(). This commit therefore makes that change. Signed-off-by: Paul E.
