The CDDL does not prevent ZFS from being used in Linux. It's the GPL that prevents using CDDL code in the kernel. Oracle doesn't have any grounds to sue based on their IP. They would only be able to sue on behalf of Linux, and violation of the GPL. Although I wouldn't rule that out, it's somewhat less likely to happen.
On the other hand, I suspect RMS isn't too happy with this turn of events. The sfconservancy may be the more likely party to bring a lawsuit. I'm curious to see either of them comment on the situation.
