函数名称：添加节点到头上

函数原型：void plist_add(struct plist_node *node, struct plist_head *head)

返回类型：void

参数：

类型参数名称
struct plist_node *node
struct plist_head *head
75  struct plist_node * first, * iter, * prev = NULL
76  node_next等于node_list
78  plist_check_head(head)
79  WARN_ON(!节点不在链表上)
80  WARN_ON(!链表为空)
82  如果判断链表空则转到:ins_node
85  first等于iter等于返回第一个节点
87  循环
88  如果prio小于prio则
89  node_next等于node_list
90  退出
93  prev等于iter
94  iter等于list_entry - get the struct for this entry*@ptr: the &struct list_head pointer.*@type: the type of the struct this is embedded in.*@member: the name of the list_head within the struct.(链表后项, structplist_node, prio_list)
96  当iter不等于first循环
98  如果非prev或prio不等于prio则添加链表项
100  ins_node :
101  添加链表项
103  plist_check_head(head)
