rcu: Add READ_ONCE() to rcu_segcblist ->tails[] The rcu_segcblist structure's ->tails[] array entries are read locklessly, so this commit adds the READ_ONCE() to a load in order to avoid destructive compiler optimizations. This data race was reported by KCSAN. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
