Absolutely. CDDL is incompatible with the GPL (as a copyright licence),
because it puts additional restrictions on the code that don't exist in
the GPL. Also, ZFS may include Sun patents that are licensed through
the CDDL for that code _only_ (i.e. Sun ZFS code, most likely in its
unmodified form). Meaning, even creating a "clone" (i.e. a different,
functionally equivalent implementation) may be a problem (depending on
the existence of Sun patents inside ZFS).

Sure. But don't keep you hopes up. Unless Sun release ZFS under the GPL
(fat chance, pigs flying etc.), it won't be part of Linux any time
soon. The other option is that Linux gets relicensed under, say GPL3
(which doesn't exist yet and may not be compatible with CDDL anyway).
This is close to impossible, because not all copyright holders in the
Linux kernel can (or would) give their permission for such a change.
