--- Comment #1 from Sam James <sjames at gcc dot gnu.org> ---
The header does:

#ifdef __clang__
#define ___bpf_field_ref1(field)        (field)
#define ___bpf_field_ref2(type, field)  (___bpf_typeof(type)->field)
#else
#define ___bpf_field_ref1(field)        (&(field))
#define ___bpf_field_ref2(type, field)  (&(___bpf_typeof(type)->field))
#endif

which comes from
