モジュールの初期化および終了関数にそれぞれ `__init` と `__exit` を指定 した．これらマクロを使用していなくても大きな問題は発生しないと考えられ るが，一般的な作法として追加した． これらマクロの説明は以下を参照: * https://tldp.org/LDP/lkmpg/2.4/html/x281.htm * https://fastbitlab.com/linux-device-driver-programming-lecture-18-__init-and-__exit-macros/ * https://shnoh171.github.io/linux%20kernel/2019/09/01/linux-kernel-module-basics.html
