名称描述
wq_select_unbound_cpuWhen queueing an unbound work item to a wq, prefer local CPU if allowed* by wq_unbound_cpumask. Otherwise, round robin among the allowed ones to* avoid perturbing sensitive tasks.
blk_mq_hctx_next_cpuIt'd be great if the workqueue API had a way to pass* in a mask and had some smarts for more clever placement.* For now we just round-robin here, switching for every* BLK_MQ_CPU_WORK_BATCH queued items.
