It might be, I revisited a month back and could no longer trigger the bug, so it's possible unrelated changes or kernel changes have fixed the overlayfs copy-up semantics in cases where it would cause issues with QEMU. If I ever see it again I can resubmit evidence, so it may be better off closed.

Yes, that compile error with QEMU + recent kernel headers is a bit annoying, and AFAICS it is not fixed in Debian yet. Would you mind writing a test case for this bug that you fixed, to prevent this accidentally being broken in future again? Please note that 9pfs is currently only been taken care
