    Subject[RFC PATCH] libtraceevent: Increase libtraceevent logging when verbose
    From
    libtraceevent has added more levels of debug printout and with changes
    like:
    https://lore.kernel.org/linux-trace-devel/20210507095022.1079364-3-tz.stoyanov@gmail.com
    previously generated output like "registering plugin" is no longer
    displayed. This change makes it so that if perf's verbose debug output
    is enabled then the debug and info libtraceevent messages can be
    displayed.
    As this API isn't present in the deprecated tools version of
    libtracevent I'm uploading this as an RFC.
