    Linus Torvalds authored
    Pull tracing updates from Steven Rostedt:
     "Lots of tweaks, small fixes, optimizations, and some helper functions
      to help out the rest of the kernel to ease their use of trace events.
    
      The big change for this release is the allowing of other tracers, such
      as the latency tracers, to be used in the trace instances and allow
      for function or function graph tracing to be in the top level
      simultaneously"
