You mean "if you want to interact directly with arbitrary Linux kernel
functionality that we deem GPL-only, then you have to abide by its licens=
e"


Because the GPL-only symbol export makes it seem like most symbols are
NOT GPL-only. Why is there any distinction at all?


Why does the Linux kernel allow loading of non-GPL modules? Maybe it's
because the end user is ALLOWED to load non-GPL modules?


ZFS is ALLOWED to exist in the Linux ecosystem. It is not ALLOWED to be
distributed with the Linux kernel in binary form. The source trees can
not be merged without patent issues. No one is debating this.


What the issue here, is that previously a non-GPL module was working,
and now is not. NVIDIA is running GPL code?

Asked last week for a source on this and you haven't provided any.
However, the SFLC plainly disagrees with you.

The previous situation was the STATUS QUO for years. Since 2012 we had
working ZFS on Linux with SIMD extensions, and now suddenly being told
that it is a license violation.


This is why people are upset at you, because you stand here waving a big
stick and telling us that we are breaking some rule you have merely
imagined.

Message received, loud and clear. We will go back to wrapping GPL-only
exports in our SPL (GPL licensed) kernel module. The Condom Works!


Best of luck with your windmills, Don Quixote.
