Finding the Link, the Hard Link

OK, sorry for the sappy subject but oh well.

So I am having a question and problem.  What I am doing is writing a 
script to parse over 2 loop file systems, and check for changes.  
Simple, no?  Well I thought so until I ran into the HardLink.  This 
would be able to be ignored and just put 2 copies of the file in the 
loop filesystem, however we are pressed for space and every 4k matters.  
So I ask, is there a way to tell the difference between the real file, 
and a hard link?

eg.
/etc/passwd and /etc/passwd.hl

The .hl was made with ln, now how can I tell that it is, or was made 
with ln, a hard link?
