    ftrace: Do not run selftest if command line parameter is set · f1ed7c74
    Steven Rostedt (Red Hat) authored
    If the kernel command line ftrace filter parameters are set
    (ftrace_filter or ftrace_notrace), force the function self test to
    pass, with a warning why it was forced.
    If the user adds a filter to the kernel command line, it is assumed
    that they know what they are doing, and the self test should just not
    run instead of failing (which disables function tracing) or clearing
    the filter, as that will probably annoy the user.
    If the user wants the selftest to run, the message will tell them why
    it did not.
