返回类型：void

参数：

类型参数名称
struct bio_set *bs
362  如果WARN_ON_ONCE(!rescue_workqueue)则返回
375  bio_list_init( & punt)
376  bio_list_init( & nopunt)
378  当bio等于bio_list_pop( & bio_list[0])循环
379  bio_list_add(bi_pool == bs ? & punt : & nopunt, bio)
380  bio_list[0]等于nopunt
382  bio_list_init( & nopunt)
383  当bio等于bio_list_pop( & bio_list[1])循环
384  bio_list_add(bi_pool == bs ? & punt : & nopunt, bio)
385  bio_list[1]等于nopunt
387  加自旋锁
388  bio_list_merge( & rescue_list, & punt)
389  自旋锁解锁
