Indeed, that confirms what I thought.

This looks like buggy or at least borderline behavior from Btrfs.
However, it seems that this ‘nlink’ test can be sidestepped altogether.

Could you apply this last patch and run:

  make check TESTS=tests/nar.scm

again?

If it works for you, I’ll just apply it.

Thanks!
