Use vendor channel interface to configure your driver.
What is that? configfs or something else?
An immediate answer without digging into your code is Matan's KABI work.
https://github.com/matanb10/linux/tree/abi-devel-latest
Until that code is formally accepted and actually in the kernel we can't
base our changes that are ready to go now (for 4.12) on it.
However, I have an question, how do you ensure that user memory has no
users without refcounts? Will it be possible to dereg the memory despite
the fact that there are users?
Mike can correct me if I'm wrong but it is still refcounted. Just not
per CPU, global if you will.
