void (*sync
222  first等于链表后项
223  last等于链表前项
231  INIT_LIST_HEAD_RCU - Initialize a list_head visible to RCU readers*@list: list to be initialized* You should instead use INIT_LIST_HEAD() for normal initialization and* cleanup tasks, when readers have no access to the list being initialized
240  sync()
