Steven Rostedt (Red Hat) cf6ab6d914 tracing: Add ref count to tracer for when they are being read by pipe ... When one of the trace pipe files are being read (by either the trace_pipe or trace_pipe_raw), do not allow the current_trace to change. By adding a ref count that is incremented when the pipe files are opened, will prevent the current_trace from being changed. This will allow for the removal of the global trace_types_lock from reading the pipe buffers (which is currently a bottle neck).
