You should be able to remove the /tmp entry as root.

Check http://en.wikipedia.org/wiki/Inode for more details.

I think the salient point from that page is this:
"Files can have multiple names. If multiple names hard link to the same
inode then the names are equivalent. I.e., the first to be created has
no special status. This is unlike symbolic links, which depend on the
original name, not the inode (number)."

Kind of like looking at Denali from the north and the south. It looks
different depending on where you stand, but it's the same rock...
