ZFS is licensed under the Common Development and Distribution License (CDDL),
and the Linux kernel is licensed under the GNU General Public License Version 2
(GPL-2). While both are free open source licenses they are restrictive
licenses. The combination of them causes problems because it prevents using
pieces of code exclusively available under one license with pieces of code
exclusively available under the other in the same binary.

Please be aware that distributing of the binaries may lead to infringing.
