Sorry about that I didn't Cc the proper list at first, but it could be checked by using lore: https://lore.kernel.org/linux-unionfs/20260623084337.54344-1-laoar.shao@gmail.com/T/#u This topic is very specific to overlayfs details, I'm not sure how I could say the background in brief. But almost every single container user uses overlayfs now, so in order to be responsible for end users, container runtimes and applications, I used some aggressive way this time. Thanks, Gao Xiang
