      tracepoint, vfs, sched: Add exec() tracepoint · 4ff16c25
      David Smith authored
      Added a minimal exec tracepoint. Exec is an important major event
      in the life of a task, like fork(), clone() or exit(), all of
      which we already trace.
      
      [ We also do scheduling re-balancing during exec() - so it's useful
        from a scheduler instrumentation POV as well. ]
      
      If you want to watch a task start up, when it gets exec'ed is a good place
      to start.  With the addition of this tracepoint, exec's can be monitored
      and better picture of general system activity can be obtained. This
      tracepoint will also enable better process life tracking, allowing you to
      answer questions like "what process keeps starting up binary X?".
      
      This tracepoint can also be useful in ftrace filtering and trigger
      conditions: i.e. starting or stopping filtering when exec is called.
