Not really. Think about it. Only to remove restrictions from a license do you need permission from the existing developers. To introduce extra restrictions you don&#x27;t need anyone&#x27;s permission. If Linus chooses to accept a single patch that&#x27;s GPLv3, the kernel is GPLv3 from that point forward.<p>Linus has in fact done this to quite a bit of MIT licensed code.<p>Of course it only applies to future versions, and you could conceivably make versions that have those patches removed.
