参数：

类型参数名称
struct kobj_uevent_env *env
const char *action_string
const char *devpath
312  struct sk_buff * skb = NULL
314  retval等于0
318  uevent_sock等于sk
320  如果非netlink_has_listeners(uevent_sock, 1)则继续下一循环
323  如果非skb则
324  retval等于负ENOMEM
325  skb等于alloc_uevent_skb(env, action_string, devpath)
326  如果非skb则继续下一循环
330  retval等于netlink_broadcast(uevent_sock, 引用缓存, 0, 1, GFP_KERNEL)
333  如果retval恒等于负ENOBUFS或retval恒等于负ESRCH则retval等于0
