Mark this parameter as nullable to\nmake verifier aware of such possibility.\nOtherwise, NULL check in the test_1() code:\n\n SEC(\"struct_ops/test_1\")\n int BPF_PROG(test_1, struct bpf_dummy_ops_state *state)\n {\n if (!state)\n return ...;\n\n ... access state ...\n }\n\nMight be removed by verifier, thus triggering NULL pointer dereference\nunder certain conditions."
