Steven Rostedt 0a8f11f856 tracing: Do not take trace_event_sem in print_event_fields() ... On some paths in print_event_fields() it takes the trace_event_sem for read, even though it should always be held when the function is called. Remove the taking of that mutex and add a lockdep_assert_held_read() to make sure the trace_event_sem is held when print_event_fields() is called.
