    ftrace: add ftrace_kill_atomic · a2bb6a3d
    Steven Rostedt authored
    It has been suggested that I add a way to disable the function tracer
    on an oops. This code adds a ftrace_kill_atomic. It is not meant to be
    used in normal situations. It will disable the ftrace tracer, but will
    not perform the nice shutdown that requires scheduling.
