Hi Fedora legal,
the code mentioned by Elena is not yet available in the git repo,
but there seems to be earlier code there.

In both repositories there's a commit titled "Finish GPL/CDDL splitting
work".
It seems to me that Oracle plans to at least make the kernel part GPL, and
thereby increase the chances of merging this upstream.
Did anybody from Fedora legal take a look or consider including that in
a future release?
