    tracing: Separate out trace events from global variables · ae63b31e

    The trace events for ftrace are all defined via global variables.
    The arrays of events and event systems are linked to a global list.
    This prevents multiple users of the event system (what to enable and
    what not to).
    
    By adding descriptors to represent the event/file relation, as well
    as to which trace_array descriptor they are associated with, allows
    for more than one set of events to be defined. Once the trace events
    files have a link between the trace event and the trace_array they
    are associated with, we can create multiple trace_arrays that can
    record separate events in separate buffers.
