The Linux Kernel is licensed under the GNU General Public License
Version 2 (`GPLv2 <http://www.gnu.org/licenses/gpl2.html>`__). While
both (OpenZFS and Linux Kernel) 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.
In the case of the Linux Kernel, this prevents us from distributing OpenZFS
as part of the Linux Kernel binary. However, there is nothing in either license
that prevents distributing it in the form of a binary module or in the form
of source code.

Licensing
---------
ZFS is licensed under the Common Development and Distribution License
(`CDDL <http://hub.opensolaris.org/bin/view/Main/opensolaris_license>`__),
and the Linux kernel is licensed under the GNU General Public License
Version 2 (`GPLv2 <http://www.gnu.org/licenses/gpl2.html>`__). 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. In the case of
the kernel, this prevents us from distributing ZFS on Linux as part of
the kernel binary. However, there is nothing in either license that
prevents distributing it in the form of a binary module or in the form
of source code.
