    perf annotate: Don't return -1 for error when doing BPF disassembly · 11aad897
    Arnaldo Carvalho de Melo authored
    Return errno when open_memstream() fails and add two new speciall error
    codes for when an invalid, non BPF file or one without BTF is passed to
    symbol__disassemble_bpf(), so that its callers can rely on
    symbol__strerror_disassemble() to convert that to a human readable error
    message that can help figure out what is wrong, with hints even.
