函数原型：static void add_node(struct gcov_info *info)

返回类型：void

参数：

类型参数名称

572  filename等于kstrdup(Interface to access gcov_info data , GFP_KERNEL)
573  如果非filename则返回
575  parent等于root_node
577  以next等于strchr - Find the first occurrence of the character c in the string s.*@s: the string to be searched*@c: the character to search for循环
