Also, the check for link count >= 2 might also be optimized to skip directories (whose link count is always > 1, but since directories can't be hard-linked, it is not worth looking up their id).
Does POSIX mandate that directories cannot be hard-linked? I think NTFS can create hard links to directories, and reparse points can be used as hard links.
