Andrii Nakryiko says:

====================
Based on latest feedback and discussions, this patch set implements the
following changes:

- Kconfig-provided externs have to be in .kconfig section, for which
  bpf_helpers.h provides convenient __kconfig macro (Daniel);
- instead of allowing to override Kconfig file path, switch this to ability to
  extend and override system Kconfig with user-provided custom values (Alexei);
- BTF is required when externs are used.
====================
