Author: David Smith <>

    Improved task_finder2 mmap tracking and better task_work cleanup.
    * runtime/task_finder2.c (__stp_tf_alloc_task_work): New function.
      (__stp_tf_free_task_work): Ditto.
      (__stp_tf_cancel_task_work): Ditto.
      (__stp_tf_quiesce_worker): Renamed from __stp_task_worker(). Uses
      __stp_tf_free_task_work() to free the task_work structure.
      (__stp_utrace_task_finder_target_quiesce): Uses
      __stp_tf_alloc_task_work() to allocate a task_work structure.
      (__stp_tf_mmap_worker): New task_work worker function.
      (__stp_utrace_task_finder_target_syscall_exit): If we're in an atomic
      context, use task_work_add() to call __stp_tf_mmap_worker().
      (stap_stop_task_finder): Call __stp_tf_cancel_task_work() to cancel all
      outstanding task work requests.
