    Subject[PATCH 20/28] perf report: Add report.children config option
    Date
    Add report.children config option for setting default value of
    callchain accumulation. It affects the report output only if
    perf.data contains callchain info.

    A user can write .perfconfig file like below to enable accumulation
    by default:

    $ cat ~/.perfconfig
    [report]
    children = true

    And it can be disabled through command line:

    $ perf report --no-children
