Yes it does. The out of tree drivers are responsible for keeping
themselves up to date.

Note also that this is an -rc kernel. NVIDIA is generally careful
to keep its driver building against released kernels, but with -rc
kernels we often just wait until the kernel is released, in order
to avoid too much churn. Most customers don't (and shouldn't) run
an -rc Linux kernel anyway, is why.

Anyway, no, we don't patch the upstream kernel for this kind of
issue. But thanks for thinking about it. :)

thanks,
