H A Dthis_cpu_ops.rst16 this_cpu操作
22 this_cpu操作是一种优化访问与当前执行处理器相关的每CPU变量的方法。这是通过使用段寄
25 this_cpu操作将每CPU变量的偏移量添加到处理器特定的每CPU基址上，并将该操作编码到对
42 this_cpu操作的主要用途是优化计数器操作。
44 定义了以下具有隐含抢占保护的this_cpu()操作。可以使用这些操作而不用担心抢占和中断::
63 this_cpu操作的内部工作
85 请思考下面this_cpu操作::
105 会在this_cpu指令执行的前后直接移动该进程。一般来说，这意味着每个处理器的单个计数
141 在每CPU操作的上下文中，上面表达式说明x是一个每CPU变量。大多数this_cpu操作都需要一
