The TaskScheduler keeps track of what tasks are currently schedulable. When a task is enqueued it is added to the run queue or the pending queue depending as to whether there is a runable or pending task ahead of it that violates the mutual exclusion policies. When tasks exit the scheduler re-examines the tasks on the pending queue which may now be runnable. It is important that this process is efficient such that exit events do not scan tasks that are not waiting on a particular task id or task instance to have a 0 count. More...

Detailed Description

The TaskScheduler keeps track of what tasks are currently schedulable. When a task is enqueued it is added to the run queue or the pending queue depending as to whether there is a runable or pending task ahead of it that violates the mutual exclusion policies. When tasks exit the scheduler re-examines the tasks on the pending queue which may now be runnable. It is important that this process is efficient such that exit events do not scan tasks that are not waiting on a particular task id or task instance to have a 0 count.
