H A Dxarray.rst162 内部使用xa_lock:
186 假设进入时持有xa_lock:
195 如果你想利用锁来保护你存储在XArray中的数据结构，你可以在调用xa_load()之前调用xa_lock()，然后在
225 xa_lock(&foo->array);
234 上面的例子还显示了一个常见的模式，即希望在存储端扩展xa_lock的覆盖范围，以保护与数组相关的一些统计
238 在进程上下文中使用xa_lock_irq()，在中断处理程序中使用xa_lock()。一些更常见的模式有一些辅助函数，
242 意味着你有权使用像__xa_erase()这样的函数而不占用xa_lock；xa_lock是用来进行lockdep验证的，将来也
252 你需要在修改数组的时候使用xa_lock。在对数组进行只读操作时，你可以选择使用xa_lock或RCU锁。你可以在
267 存在xa_state中供下一次尝试。这个想法是，你拿着xa_lock，尝试操作，然后放弃锁。该操作试图在持有锁的情
295 - 这个条目目前正在被一个拥有xa_lock的线程修改。在这个RCU周期结束时，包含该条目的节点可能会被释放。
