返回类型：void

参数：

类型参数名称
struct io_wq_work **workptr
3326  work等于workptr
3327  req等于container_of - cast a member of a structure out to the containing structure*@ptr: the pointer to the member.*@type: the type of the container struct this is embedded in.*@member: the name of the member within the struct.(work, structio_kiocb, work)
3328  struct io_kiocb * nxt = NULL
3329  ret等于0
3331  如果flags按位与IO_WQ_WORK_CANCEL则ret等于负ECANCELED
3334  如果非ret则
3335  has_user等于flags按位与IO_WQ_WORK_HAS_MM的值不等于0
3336  in_async = true
3337  循环
3338  ret等于io_issue_sqe(req, NULL, & nxt, false)
3344  如果ret不等于负EAGAIN则退出
3346  cond_resched()
3347  当1循环
3351  io_put_req(req)
3353  如果ret则
3354  req_set_fail_links(req)
3355  io_cqring_add_event(req, ret)
3356  io_put_req(req)
3360  如果非ret且nxt则io_wq_assign_next(workptr, nxt)
