RV per-task monitors are implemented through a monitor structure available for each task_struct. This structure is reset every time the monitor is (re-)started, to avoid inconsistencies if the monitor was activated previously. To do so, we reset the monitor on all threads using the macro for_each_process_thread. However, this macro excludes the idle tasks on each CPU. Idle tasks could be considered tasks on their own right and it should be up to the model whether to ignore them or not. Reset monitors also on the idle tasks for each present CPU whenever we reset all per-task monitors.
