    bpf tools: New API to get name from a BPF object · acf860ae
    Wang Nan authored
    Before this patch there's no way to connect a loaded bpf object
    to its source file. However, during applying perf's '--filter' to BPF
    object, without this connection makes things harder, because perf loads
    all programs together, but '--filter' setting is for each object.
    
    The API of bpf_object__open_buffer() is changed to allow passing a name.
    Fortunately, at this time there's only one user of it (perf test LLVM),
    so we change it together.
