This patch series fixes a bug reported by Hui Zhu; see proposed patches v1 and v2: https://lore.kernel.org/linux-fsdevel/20230811035705.3296-1-teawaterz@xxxxxxxxxxxxxxxxx/ https://lore.kernel.org/linux-fsdevel/20230811071519.1094-1-teawaterz@xxxxxxxxxxxxxxxxx/ I decided to go in a rather different direction for this fix, and fix a related problem at the same time. I don't think there's any urgency to rush this into Linus' tree, nor have I marked it for stable. Reasonable people may disagree.
