    perf symbols: Set the DSO long name when using symbol_conf.vmlinux_name · e7dadc00
    Arnaldo Carvalho de Melo authored
    We need to set the long name to the name specified via, for instance,
    'perf annotate --vmlinux /path/to/vmlinux', if not it will remain as
    '[kernel.kallsyms]' and that will make annotate fail when passing this
    as the vmlinux name in the call to objdump.
    
    The way this is setup grew unwieldly and dso__load_vmlinux is the
    function that should allocate space for the long name, with callers not
    assuming that filenames should be allocated somehow by then (strdup,
    dso__build_id_filename, etc).
    
    For now this is the minimalistic patch, a proper fix for .36 will be
    made.
