函数名称：fill_kobj_path

函数原型：static void fill_kobj_path(struct kobject *kobj, char *path, int length)

返回类型：void

参数：

类型参数名称
struct kobject *kobj
char *path
intlength
151  length先自减
152  以parent循环
153  cur等于strlen(kobject_name(parent))
155  length减等于cur
156  内存复制(path + length, kobject_name(parent), cur)
157  *path加length先自减的和等于'/'
160  pr_debug("kobject: '%s' (%p): %s: path = '%s'\n", kobject_name(kobj), kobj, __func__, path)
