    Merge tag 'trace-v4.9-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/linux-trace
    
    Pull tracing fixes from Steven Rostedt:
     "Alexei discovered a race condition in modules failing to load that can
      cause a ftrace check to trigger and disable ftrace.
    
      This is because of the way modules are registered to ftrace. Their
      functions are loaded in the ftrace function tables but set to
      "disabled" since they are still in the process of being loaded by the
      module. After the module is finished, it calls back into the ftrace
      infrastructure to enable it.
    
      Looking deeper into the locations that access all the functions in the
      table, I found more locations that should ignore the disabled ones"
