Omitting oracle.com address of Jens, as its not valid. Adding in ax...@kernel.dk, as I am not sure whether the oracle.com address from Jens is actually valid / up to date.

I'll seek confirmation with Martin > Steigerwald. Which entry to you refer to? I assume the one about hash.h. Well the file has in its header: /* Fast hashing routine for a long. (C) 2002 William Lee Irwin III, IBM */ * Knuth recommends primes in approximately golden ratio to the maximum * integer representable by a machine word for multiplicative hashing. * Chuck Lever verified the effectiveness of this technique: * http://www.citi.umich.edu/techreports/reports/citi-tr-00-1.pdf * These primes are chosen to be bit-sparse, that is operations on * them can use shifts and additions instead of multiplications for * machines where multiplications are slow. */ It has been quite a while ago. I bet back then I did not regard this as license information since it does not specify a license. Thus I assumed it to be GPL-2 as the other files which have no license boiler plate. I.e.: Check file is it has different license, if not, then assume it has license as specified in COPYING. Not specifying a license can however also mean in this context that it has no license as the file contains copyright information from another author. Of course I can update copyright file in case my conclusion from a long time ago was wrong.
