Since we don't have a user for the new UAPI right now, perhaps we can
put the new UAPI behind the staging Kconfig until it will get a
real/production user.
On the other hand, I had unpleasant experience with having UAPI gated by
staging Kconfig for other kernel subsystem in a sense that it
permanently stays a staging UAPI because nobody has time for unstaging it.
I see a common demand in this new UAPI which only becomes stronger over
time. Won't hurt to refresh this patchset. I had a rebased version
locally, but likely it needs to be rebased again. Will try to allocate
time for this.
