Pretty much my view as well. If Linux becomes incompatible with ZFS in any way, I'll switch to FreeBSD.

That said, after the Oracle Java debacle, I can see why Linus would not be receptive towards merging ZFS into the kernel. I just wish he argued the point on legal issues alone instead of making up stories about non-existent technical flaws in ZFS. The whole thing is basically a work of art. Oracle should consider GPL-ing it and integrating it into Linux directly.
