Torvald's has said in the past he won't ever change the license of Linux. The GPL normally has a clause that says the source code has to be licensed under "this license or a newer version of the GPL". Projects that have moved from GPLv2 to GPLv3 did so because of this clause in the license. Torvalds specifically removed this clause. I doubt Torvalds is concerned about whether or not users can use ZFS. He's defended the existence of closed source kernel modules (ex graphics drivers, network drivers). There's even the quote in the article that Torvald's didn't consider Andrew File System derivative of the kernel. Further, users can use ZFS-FUSE; there's no question that ZFS-FUSE doesn't infringe. Finally, Oracle owns sole copyright to ZFS; they can re-licence it. Linux will never move from GPLv2 and I'd be really surprised if Torvalds saw the ZFS issue as a problem with the GPLv2 and not an Oracle problem.
