H A Dworkqueue.rst139 参数 - ``@name`` , ``@flags`` 和 ``@max_active`` 。
143 工作项属性的域。 ``@flags`` 和 ``@max_active`` 控制着工作
155 BH工作队列的 ``max_active`` 值必须为0，且只能单独或和
201 ``max_active``
204 ``@max_active`` 决定了每个CPU可以分配给wq的工作项的最大执行上
205 下文数量。例如，如果 ``@max_active`` 为16 ，每个CPU最多可以同
208 ``@max_active`` 的最大限制是512，当指定为0时使用的默认值是256。
217 顺序处理带来的严格执行顺序。``@max_active`` 为1和 ``WQ_UNBOUND``
245 And with cmwq with ``@max_active`` >= 3, ::
