Cassandraパッチ適用時のエラー

Question

Cassandra 3.8にCassandraパッチ（https://issues.apache.org/jira/browse/CASSANDRA-11569）を適用しようとしています。私はgit apply CASSANDRA-11569.patch -vを使用してパッチを適用しようとすると、https://github.com/apache/cassandra/releases/tag/cassandra-3.8からソースコードをダウンロードしたI取得するには、次のエラー

誰かがここで問題に何ができるかを説明していただけますか？

このパッチをCassandra 3.8に適用する必要はありません。 3.8には既にパッチが適用されています。
