Now that call_rcu()'s callback is not invoked until after all 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, synchronize_rcu() can be used in place of synchronize_rcu_bh(). This commit therefore makes these changes. Signed-off-by: Paul E. McKenney <paulmck@linux.ibm.com> Cc: "David S.
