It's impossible to relicense Linux. Linus has talked about this in the past: he'd have to track down literally thousands of contributors to get their permission. Many of them are probably impossible to track down, some are surely dead. There's no feasible way to relicense a project like Linux. ZFS, OTOH, is owned by a single entity, so relicensing it would be simple. It should be completely possible to make a new license that grants a patent license but is also GPL compatible.
