Force the use of per-cpu mmaps. By default, when tasks are specified (i.e. -p,
-t or -u options) per-thread mmaps are created. This option overrides that and
forces per-cpu mmaps. A side-effect of that is that inheritance is
automatically enabled. Add the -i option also to disable inheritance.
--per-thread::
Use per-thread mmaps. By default per-cpu mmaps are created. This option
overrides that and uses per-thread mmaps. A side-effect of that is that
inheritance is automatically disabled. --per-thread is ignored with a warning
