    v3: zhaolei@cn.fujitsu.com: Change TRACE_EVENT definition to new format
        introduced by Steven Rostedt: consolidate trace and trace_event headers
    v2: kosaki@jp.fujitsu.com: print the function names instead of addr, and zap
        the work addr
    v1: zhaolei@cn.fujitsu.com: Make workqueue tracepoints use TRACE_EVENT macro
    
    TRACE_EVENT is a more generic way to define tracepoints.
    Doing so adds these new capabilities to the tracepoints:
    
      - zero-copy and per-cpu splice() tracing
      - binary tracing without printf overhead
      - structured logging records exposed under /debug/tracing/events
      - trace events embedded in function tracer output and other plugins
      - user-defined, per tracepoint filter expressions
    
    Then, this patch converts DEFINE_TRACE to TRACE_EVENT in workqueue related
    tracepoints.
