539  如果非是错误或空则返回:错误号
542  如果错误不等于负EAGAIN且错误不等于负ENOENT则返回:错误指示
545  new_tbl等于rht_dereference_rcu(future_tbl, ht)
546  如果new_tbl则返回:new_tbl
549  如果错误不等于负ENOENT则返回:错误指示
552  如果此条件成立可能性小(为编译器优化)(表溢出)则返回:错误号
555  如果此条件成立可能性小(为编译器优化)(ht_grow_above_100 - returns true if nelems > table-size*@ht: hash table*@tbl: current table)则返回:错误号
558  head等于rht_ptr(bkt, tbl, hash)
560  RCU_INIT_POINTER() - initialize an RCU protected pointer*@p: The pointer to be initialized.*@v: The value to initialized the pointer to.* Initialize an RCU-protected pointer in special cases where readers(next, head)
561  如果rhlist则
564  list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.(obj, structrhlist_head, rhead)
565  RCU_INIT_POINTER() - initialize an RCU protected pointer*@p: The pointer to be initialized.*@v: The value to initialized the pointer to.* Initialize an RCU-protected pointer in special cases where readers(next, NULL)
