+       Sometimes this is not the desired action. Setting ``exit_all`` will
+       instead make fio terminate all jobs in the same group. The option
+        ``exit_what`` allows to control which jobs get terminated when ``exitall`` is
+        enabled. The default is ``group`` and does not change the behaviour of
+        ``exitall``. The setting ``all`` terminates all jobs. The setting ``stonewall``
+        terminates all currently running jobs across all groups and continues execution
+        with the next stonewalled group.
