As I suspected, Linus cannot 'remove' his code from the Linux kernel. Once part of the GPL kernel, it is forever available under the GPL. If it was an 'individual license' as you purported earlier, this wouldn't be the case.
I agree that Linux can take his GPL contributions and place them elsewhere (proprietary, BSD, etc.). But that's not 'removing' them from Linux.
Sorry, that's what I meant. I was not trying to imply he can just pull his contributions, say "f$%^ you all" to the rest of the team and pull a SCO if they don't remove his code.
