Sorry, my previous reply was rejected by the list because it wasn't in plain text. Let's try again. librbd.cc: /* * Ceph - scalable distributed file system * * Copyright (C) 2011 New Dream Network * * This is free software; you can redistribute it and/or * modify it under the terms of the GNU General Public * License version 2.1, as published by the Free Software * Foundation.

See file COPYING. * */ These are the three that I've noticed poking around librbd so far. My understanding from COPYING is that they should be LGPL, but these copyright headers obviously state GPL instead. I'm just trying to understand definitely which it is. :) If a change is in order, of course I'll be happy to make the change myself and submit a pull request if you like.
