      Pull tracing fixes from Steven Rostedt:
       "A few tracing fixes:
      
         - Remove lockdown from tracefs itself and moved it to the trace
           directory. Have the open functions there do the lockdown checks.
      
         - Fix a few races with opening an instance file and the instance
           being deleted (Discovered during the lockdown updates). Kept
           separate from the clean up code such that they can be backported to
           stable easier.
      
         - Clean up and consolidated the checks done when opening a trace
           file, as there were multiple checks that need to be done, and it
           did not make sense having them done in each open instance.
      
         - Fix a regression in the record mcount code.
      
         - Small hw_lat detector tracer fixes.
      
         - A trace_pipe read fix due to not initializing trace_seq"
