21 理解驱动模型和建立在其上的kobject抽象的部分的困难在于，没有明显的切入点。
26 - 一个kobject是一个kobject结构体类型的对象。Kobjects有一个名字和一个
27 引用计数。一个kobject也有一个父指针（允许对象被排列成层次结构），一个
33 任何结构体都 **不应该** 有一个以上的kobject嵌入其中。如果有的话，对象的引用计
36 - ktype是嵌入一个kobject的对象的类型。每个嵌入kobject的结构体都需要一个
37 相应的ktype。ktype控制着kobject在被创建和销毁时的行为。
41 但你可以安全地忽略这个实现细节，因为kset的核心代码会自动处理这个kobject。
