【Issue#1329 動作確認】
□ テスト内容
1. 以下のLTPを300回連続実行し、Issueで報告された症状が発生しないことを確認
- msgctl11
なお、本テストケースはapollo上では別の不具合によりテストが動作しないため、テスト対象から除外した
2. 以下のLTPを用いて既存のfork機能に影響が無いことを確認
- fork01
- fork02
- fork03
- fork04
- fork05
- fork06
- fork07
- fork08
- fork09
- fork10
- fork11
□ 実行手順
$ make test
McKernelのインストール先や、OSTEST, LTPの配置場所は、
$HOME/.mck_test_config を参照している
.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
□ 実行結果
x86_64_result.log aarch64_result.log 参照。
すべての項目をPASSしていることを確認。
