&gt; What about the opinion of the developers who wrote the module and licensed it under CDDL?<p>We are okay with it.<p>Although ZFS developers on all open source platforms are considered OpenZFS developers, I am explicitly listed on the wiki:<p><a href="http:&#x2F;&#x2F;open-zfs.org&#x2F;wiki&#x2F;Contributors#Richard_Yao" rel="nofollow">http:&#x2F;&#x2F;open-zfs.org&#x2F;wiki&#x2F;Contributors#Richard_Yao</a><p>I am also the #2 ZFSOnLinux contributor by commit count according to github&#x27;s statistics and I have maintained that position for years:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;zfsonlinux&#x2F;zfs&#x2F;graphs&#x2F;contributors" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;zfsonlinux&#x2F;zfs&#x2F;graphs&#x2F;contributors</a><p>If any of the other OpenZFS developers had a problem with Linux distributions shipping the OpenZFS code, I ought to have heard about that by now. So far, every OpenZFS developer on every other platform that I meet is happy that the code is available on Linux. I have even met employees at Oracle that are happy about it. While that is not an official stance of Oracle, Oracle itself publishes a dtrace module under the CDDL for use on Linux, so it would be strange to think that they would have a problem with shipping a port of the ZFS driver from the original OpenSolaris codebase under the original license for Linux, especially when it benefits Oracle Linux.
