xfstests license clarification?

[Eric Sandeen]

Since most of the scripts themselves in xfstests make no mention of
redistribution, and only say "copyright sgi, all rights reserved" etc:

#-----------------------------------------------------------------------
#  Copyright (c) 2006 Silicon Graphics, Inc.  All Rights Reserved.
#-----------------------------------------------------------------------

do we need to do anything in terms of making this look more like Free
Software (assuming that's the intent?)

It might be a rats-nest, there are a several testcases in src/ gleaned
from mailing lists & bugs with little or no attribution; OTOH maybe this
stuff is trivial enough that it doesn't warrant copyright, I dunno.

Is it worth trying to clarify the license on the collection, or is this
just a can of worms?
