rcu: Apply ACCESS_ONCE() to rcu_boost() return value Both TINY_RCU's and TREE_RCU's implementations of rcu_boost() access the ->boost_tasks and ->exp_tasks fields without preventing concurrent changes to these fields. This commit therefore applies ACCESS_ONCE in order to prevent compiler mischief. Signed-off-by: Paul E. McKenney <paul.mckenney@linaro.org> Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com>
