Arnaldo Carvalho de Melo 11aad897f6 perf annotate: Don't return -1 for error when doing BPF disassembly ... 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.
