+【Issue#1377 動作確認】
+□ テスト内容
+1. Issue 指摘事項の再現確認
+   現象はタイミングに依存し、ARM64環境でdirtyc0wを繰り返し実行した際に、
+   数回〜数十回に１回程度発生する。
+   問題の発生はタイミングに依存するため、dirtyc0wを十分な回数繰り返し
+   実行し、問題が再発しないことを確認する。
+
+C1377T01 dirtyc0wを1000回連続実行し、全てPASSすることを確認
+
+2. LTP を用いて既存処理に影響しないことを確認
+   プロセスの終了ステータスを変更したため、修正が既存処理に影響しないことを
+   wait系システムコールのLTPを用いて確認する。
+C1377T02 wait02: waitの基本機能の確認

+□ 実行手順
+$ make test
+
+McKernelのインストール先や LTP の配置場所は、$HOME/.mck_test_config を
+参照する。.mck_test_config は、McKernel をビルドした際に生成される
+mck_test_config.sample ファイルを $HOME にコピーし、適宜編集すること。
+
+□ 実行結果
+C1377_x86_64.txt(x86_64実行結果)、C1377_arm64.txt(arm64実行結果)参照。
+全ての項目が PASS していることを確認。

+C1399T01:
+  1. struct robust_list_head のサイズよりも1大きい値をサイズとして指定して
+    set_robsut_list を呼び出し、EINVALで失敗することを確認
+  2. struct robust_list_head のサイズよりも1小さい値をサイズとして指定して
+    set_robsut_list を呼び出し、EINVALで失敗することを確認
+
+2. 以下のLTPを用いて既存のrobust_list機能に影響が無いことを確認
+  - set_robst_list01
+  - get_robst_list01
+
+□ 実行手順
+$ make test

+□ テスト内容
+1. 本修正ではmcexecにてSIGTSTP, SIGTTIN, SIGTTOU を補足しないようにする
+  修正を実施した。
+  上記のシグナルのデフォルト動作はプロセスの停止である。
+  それぞれのシグナルについて、以下を確認する。
+	- 実行中のMcKernelプロセスに通知した際、通知先のプロセスが停止する
+	- 停止されたプロセスに対してSIGCONTを通知することで、プロセスが再開できる
+
+C1425T01: SIGTSTP の動作を確認
+C1425T02: SIGTTIN の動作を確認
+C1425T03: SIGTTOU の動作を確認
