Modify mkdir.

This would seem to be only a matter of creating a third link (in addition
to the 2 that get created now "." and "..") which would be "..." for
grandparent etc.  This would require extra directory entries for the
newly-created entries, one for each "parent" directory that exists.

Where do you stop though?  All the way to the root directory?

There's nothing special about . and ..  There just directory entries
with the same inode number (links) to another directory entry.
