What if I take the kernel from before that notice was added?
Then there would be nothing at all specifying that only the GPL v2 should be 
used.


I also would also like to poit out that the GPL under section 0 says:

This License applies to any program or other work which contains a notice 
placed by the copyright holder saying it may be distributed under the terms 
of this General Public License.

Such a notice is not present for most of the files in the kernel sorce.


What if Torvalds would add want to relicense Linux under the GPL v3, could he 
change the COPYING file without the permission of all the people that have 
added code to the kernel without specifying a license?
