What is the case for > fast-tracking it into 5.12? Andrew, As Jason and Wei pointed out, I think some userspace still got corrupted data without this series when using hugetlb backend. I don't think it'll suite for a late RC release but it'll still be great if it can be considered as an early rc candidate, ideally rc1 of course. If you prefer the other way, I can also repost it before 5.13 merge window opens. Thanks, -- Peter Xu
