rcu: Add READ_ONCE() to rcu_data ->gpwrap The rcu_data structure's ->gpwrap field is read locklessly, and so this commit adds the required READ_ONCE() to a pair of laods in order to avoid destructive compiler optimizations. This data race was reported by KCSAN. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
