I'd think so, we have few static inlines in kernel uapi headers.

  ordered accesses to the rings) compiler.h (for one unliekly and one
  likely with a tiny performance impact, if any) and list.h (some
  extra functions). What to do with these (and the header files they
  include) as they need to be dual licensed for libbpf.so?

Indeed, but I think we already have that problem, we include barrier.h
indirectly for the perf ring helper which in turn includes compiler.h
and list.h is included directly.

Thanks for the work!
