The reproducer consists in a crafted disk/btrfs image and C test-case.
This has not been helpful.
In Bionic, the crafted disk/btrfs image does not even mount.
In Focal/Groovy it does mount, but the test-case does not trigger any errors.
Anyway, the behavior is the same in the original/patched kernels.
No regressions.
