No, staging is for gettingn code into, or out of, the kernel tree, not
for anything else.

I have allowed it to be used to hold drivers in that are not
"acceptable", while another driver was written by others from scratch to
work properly on that hardware, and then the original one is dropped.
That's ok, as there is a time-limit on how long the code lives in the
staging tree.

But to try to use it to create a multi-os solution, no, that's not what
staging is for.

Also, please review the past multi-os driver initiatives that have
sprung up over the years (about 1 every 10 years it seems). Please
learn from the past as to why those have failed every single time, and
why we don't want to even try to do that again.
