> Subject: [PATCH 2/2] bpf: remove use of weak functions
>
> Weak functions don't work well with static libraries and require the use of
> "whole-archive" flag to ensure that the correct function is used when
> linking. Since the weak function is only used as a placeholder within this
> library alone, we can replace it with a non-weak version protected using
> preprocessor ifdefs.
