generic/002 is quite an old test case, and some of its code differs
from the current standard conventions in fstests. If you just want
to add it to the "hardlink" group, updating the group is sufficient.

However, if you'd like to take this opportunity to refactor some of
the code, besides your changes, you can refer to the review points
on [PATCH 2/2] as well as using _require_test_program "lstat64"

Thanks,
Zorro
