extended attribute that points back to its parent inode'.
There's currently (afaict) no Linux kernel implementation of this.

Work on the Linux port of this feature stopped when SGI closed the
Melbourne engineering office where people were working on it.
Fortunately SGI did publish the latest development state of it for
others to continue. I've attached my local copy in case you're
interested on finishing this.
Thanks Christoph, I'll take a look.
