返回类型：int

参数：

类型参数名称
struct sock *usk
struct kobj_uevent_env *env
const char *action_string
const char *devpath
346  owning_user_ns等于 Owning user namespace
347  struct sk_buff * skb = NULL
348  ret等于0

356  parms等于NETLINK_CB(skb)
361  root_uid等于make_kuid(owning_user_ns, 0)
362  如果uid_valid(root_uid)则uid等于root_uid
366  root_gid等于make_kgid(owning_user_ns, 0)
367  如果gid_valid(root_gid)则gid等于root_gid
371  ret等于netlink_broadcast(usk, skb, 0, 1, GFP_KERNEL)
373  如果ret恒等于负ENOBUFS或ret恒等于负ESRCH则ret等于0
