I'm a little unsure about the commit message of patch 2, as I commented on, but the code all looks good to me. I don't think the comment in the commit message matters too much; whether your commit message addresses the weird case I mentioned, I feel the code handles it just fine. So I'll leave it up to you to decide whether to tweak the commit message or not. Anyway, after you decide on that, feel free to apply my Reviewed-by: Elijah Newren <newren@xxxxxxxxx> Thanks for investigating, for tracking down all the return codes and how to propagate them, and getting it all fixed up!
