I am not sure I understand what you mean. Normally, with rt_task_hook,
the hook is called for all switches between Xenomai scheduler tasks.
So, when switching from secondary mode to primary mode, there should be
only one hook call: for the switch from "root thread", that is Linux, to
the real-time task itself. Are you sure this is not this call that you
are seeing?
