rcu: Add *_ONCE() to rcu_node ->boost_kthread_status The rcu_node structure's ->boost_kthread_status field is accessed locklessly, so this commit causes all updates to use WRITE_ONCE() and all reads to use READ_ONCE(). This data race was reported by KCSAN. Not appropriate for backporting due to failure being unlikely. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
