Just chiming in here, not really because of any association with the
copyleft-next license (or GPLv2 for that matter) but because of
general personal immersion in open source licensing. I would think
that code interacting with a GPLv2-only api could be under any
GPLv2-only-compatible license, such as ISC, GPLv2-or-later, or
copyleft-next. That said, of course kernel maintainers can establish
stricter policies around acceptable forms of licensing.
