第一步，需要将代码分为内核态以及可跨内核态和用户态的两部分。内核态即包含内核头文件、数据结构以及类型的部分，跨内核和用户态的部分不能包含任何内核的东西，该部分可用于用户态测试（比如单元测试），比如本项目中本文件系统自己元数据的定义、宏的定义以及一些工具函数等。
第二步，建议将跨内核和用户态的代码打成一个库，这里我打成的是动态库，方便用户态测试。但注意，内核模块的编译不能依赖任何第三方库，必须使用内核自身的框架。所以在编译内核模块的时候这部分代码又会被编译一次，按照内核模块 Kbuild 或 XMake 编译内核模块的方式。
第三步，处理 C/C++ 符号兼容性的问题。这简单，在头文件中使用 extern "C" 即可，详见 https://blog.csdn.net/m0_46606290/article/details/119973574，本项目使用的是博客中的第四种方式。
