GNU/KFreeBSD is GNU (and BSD, MIT, and a lot of other stuff) ontop of
the FreeBSD kernel. FreeBSD kernel is not GNU and is not GPL licensed.
zfs and FreeBSD kernel is license compatible.

There is no license violation in the aggregation of GNU software with
software of other licenses.

There is no license violation in running GNU software ontop of a kernel
having a different incompatible license.

Participants of the GNU Project do work with and often contribute to
open source software under a wide range of licenses, not only GPL. It's
up to each participant which projects they want to contribute to under
which terms.

I do not see how zfs in GNU/KFreeBSD as such would be incompatible with
the GNU project. The main required freedoms of the GNU project is
fulfilled by the license and source availability of the mentioned
components, just not in a way entirely compatible with the GPL license
so you can't mix freely with GPL components within the same application
or kernel.
