It is not nonsense, and Sun went out of its way to make sure that the CDDL and GPL are incompatible.
So, all the ZFS on Linux users are okay until Oracle sees money in suing them.

Linux won't(/can't) be changing from GPLv2 any time soon though. I don't know about Sun's intentions.
What evidence is there of this?
The closest I can find is where Simon Phipps said "to be GPL compatible you actually have to be willing to have your license discarded and replaced with the GPL. It's more a Borg-like assimilation than compatibility, in my view, and pretty undesirable as it results in future code enrichment being accumulated in some other code commons." https://web.archive.org/web/20050420234857/http://blogs.sun....
