    This is a maximum number of lines of callchain printed for a single
    histogram entry. Default is 0 which means no limitation.

    + This one is mostly same as call-graph.threshold but works for
    + histogram entries. Entries have overhead lower than this percentage

    + This option is to setup the maximum allocation size of internal

    + report.children::
    + The children means that functions called from another function.
    + If this option is true, perf report cumulates callchains of children

    + Please refer to the perf-report manual. The default is true.
