The workhorse for RCU's grace-period memory ordering is the
critical section for the ``rcu_node`` structure's
``-&gt;lock``. These critical sections use helper functions for lock
``->lock``. These critical sections use helper functions for lock
acquisition, including ``raw_spin_lock_rcu_node()``,
``raw_spin_lock_irq_rcu_node()``, and ``raw_spin_lock_irqsave_rcu_node()``.
Their lock-release counterparts are ``raw_spin_unlock_rcu_node()``,

The ``WARN_ON()`` is evaluated at "the end of time",
