43 | * Important ! |

45 | * Each thread queuing memory reclamation must be registered with | |
786ee85b | 46 | * rcu_defer_register_thread(). rcu_defer_unregister_thread() should be |
90075a50 | 47 | * called before the thread exits. |

49 | * *NEVER* use defer_rcu() within a RCU read-side critical section, because this |
50 | * primitive need to call synchronize_rcu() if the thread queue is full. | |
