What's not very clear to me is that how do we check the accountings for
non-btrfs filesystems, i.e. what would cause a test failure on non-btrfs
filesystems besides an xfs_io write failure? I'd prefer a btrfs-specific
test if there's no good way to do the check. Or if we want to keep it a
generic test, some comments on the non-btrfs case would be good. I'm
fine with either way.

Thanks,
Eryu
