That's wierd.  The kvm-xfstests appliance VM that's uploaded to

https://mirrors.edge.kernel.org/pub/linux/kernel/people/tytso/kvm-xfstests/

shows the problem.  With your patch applied to the xfstests-dev
directory after checking out xfstests-bld (see [1] for more
information if you haven't used kvm-xfstests before), it's reproducible via:

kvm-xfstests -I ../out_dir/root_fs.img.amd64 --update-xfstests-tar -c 4k shared/012
