Kumar Kartikeya Dwivedi 5cdccadcac bpf: Prepare prog_test_struct kfuncs for runtime tests ... In an effort to actually test the refcounting logic at runtime, add a refcount_t member to prog_test_ref_kfunc and use it in selftests to verify and test the whole logic more exhaustively. The kfunc calls for prog_test_member do not require runtime refcounting, as they are only used for verifier selftests, not during runtime execution. Hence, their implementation now has a WARN_ON_ONCE as it is not meant to be reachable code at runtime. It is strictly used in tests triggering failure cases in the verifier. bpf_kfunc_call_memb_release is called from map free path, since prog_test_member is embedded in map value for some verifier tests, so we skip WARN_ON_ONCE for it.
