net/sched: Replace call_rcu_bh() and rcu_barrier_bh()
Now that call_rcu()'s callback is not invoked until after bh-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_bh(). Similarly, rcu_barrier() can be used in place o frcu_barrier_bh(). This commit therefore makes these changes. Signed-off-by: Paul E.
