+【Issue#1121 動作確認】
+□ テスト内容
+1. Issueで報告された再現プログラムでの確認
+RT_001: ostest-sched_setaffinity.000
+	自プロセスのaffinityの設定と取得が行えることを確認
+
+RT_002: ostest-sched_setaffinity.001
+	自プロセスのaffinityを設定し、CPUのmigrateができることを確認
+
+RT_003: ostest-sched_getaffinity.003
+	存在しないプロセスIDを指定したsched_getaffinity()を実行し、
+	-1 が返り、errnoにESRCH が設定されることを確認
+
+RT_004: ostest-sched_getaffinity.005
+	子プロセスを生成し、以下を確認
+	 - 子プロセスが親プロセスのaffinityを取得
+	 - 子プロセスが自プロセスのaffinityを取得
+	 - 親プロセス、自プロセスから取得したaffinityが等しいことを確認
+
+2. 既存のsched_setaffinity機能に影響がないことをLTPを用いて確認
+LT_001: ltp-sched_setaffinity01
+	異常な引数を指定した際に返される値と
+	設定されるerrnoが正しいことを確認 (OK 4件)
+
+□ 実行手順
+$ make test
+

+□ テスト内容
+1. g310aの実行確認
+C731T001 g310aを実行し、forkが Permission denied でエラーとなることを確認
+
+2. 既存fork機能に影響しないことをLTPを用いて確認
+C731T002 fork01 の実行確認
+  fork後に子プロセスのプロセスIDが正しいことを確認 (OK 2件)
+C731T003 fork02 の実行確認
+  fork後にwaitを行い、waitが子プロセスのPIDを返却することを確認(OK 1件)
+C731T004 fork03 の実行確認
+  子プロセスがfork後に計算を行えること、また子プロセスでのfork返却値が0で
+  あることを確認 (OK 1件)
+C731T005 fork04 の実行確認
+  forkで生成した子プロセスが環境変数を変更しても、親プロセス側の
+  環境変数に変化が無いことを確認 (OK 3件)
+C731T006 fork07 の実行確認
