DExpedited-Grace-Periods.rst351 Task A now acquires the ``rcu_state`` structure's ``->exp_mutex`` and
368 releases the ``->exp_mutex``. This results in the following state:
372 Task E can then acquire ``->exp_mutex`` and increment

421 wakeups start. This is handled by having the ``->exp_mutex`` guard
423 wakeups. The key point is that the ``->exp_mutex`` is not released until
