Thank you everyone involved in the work here, especially reviews (Sergey and Manivannan), as the series looks amazing. That said, some patches in the series do not apply cleanly against 6.5-rc1, so I need to have a closer look a little bit later, hopefully I will be able to get it in time before Bjorn sends his Pull Request. シモダさん、 一連のシリーズお疲れ様でした！ 特に、作業が少し前に開始され、レビューされるまでに時間がかかった点お手数をおかけいたしました 全ての要求変更の追加にご協力いただき、ありがとうございます。 個人的にも本当に有難いです。 ご担当いただいた仕事は素晴らしいものでした。 重ねてにはなりますが、どうもありがとう！ Thank you!

It was my pleasure to be reviewing your patchset. Thanks you very much for the patience and strong eagerness to complete the turned out to be such a long-time procedure.

That said, it's always a good idea to check the main branch from the following the repository to see which version to work against if possible.
