    Subject[PATCH 25/25] perf script: Print callchains and symbols if they exist
    Date
    From: David Ahern <dsahern@gmail.com>

    The intent of perf-script is to dump the events and information in the
    file. H/W, S/W and raw events all dump callchains if they are present;
    might as well make that the default for tracepoints too.

    v2: Only add options for sym, dso and ip if callchains are present
