函数名称：assign_irq_vector_any_locked

函数原型：static int assign_irq_vector_any_locked(struct irq_data *irqd)

返回类型：int

参数：

类型参数名称
struct irq_data *irqd
272  affmsk等于irq_data_get_affinity_mask(irqd)
273  node等于irq_data_get_node(irqd)
275  如果node恒等于NUMA_NO_NODE则转到:all
278  pumask_and - *dstp = *src1p & *src2p*@dstp: the cpumask result*@src1p: the first input*@src2p: the second input* If *@dstp is empty, returns 0, else returns 1
279  如果非assign_vector_locked(irqd, vector_searchmask)则返回:0
282  如果非assign_vector_locked(irqd, Returns a pointer to the cpumask of CPUs on Node 'node'. )则返回:0
284  all :
286  pumask_and - *dstp = *src1p & *src2p*@dstp: the cpumask result*@src1p: the first input*@src2p: the second input* If *@dstp is empty, returns 0, else returns 1
287  如果非assign_vector_locked(irqd, vector_searchmask)则返回:0
290  返回:assign_vector_locked(irqd, cpu_online_mask)
