- OpenZFS is an associated project of SPI (`Software in the Public Interest

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.
