Alexei Starovoitov fc841bcfbb bpf: Fix bpf jit kallsym access ... Jiri reported crash when JIT is on, but net.core.bpf_jit_kallsyms is off. bpf_prog_kallsyms_find() was skipping addr->bpf_prog resolution logic in oops and stack traces. That's incorrect. It should only skip addr->name resolution for 'cat /proc/kallsyms'. That's what bpf_jit_kallsyms and bpf_jit_harden protect.
