Paul E. McKenney a5b8950180 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>		2020-02-20 15:58:22 -08:00
