I have not seen the term actually used, but I think it means an inode,
that has non-zero link count, but no dentries pointing to it are to be
found.

You are probably doing the reference-counting wrong. You should check,
that when you delete a dentry, the inode's nlink count is decremented
and the inode is properly marked dirty (so the nlink count makes it to
disk).
