 4.4.7. Updating a Process Element in the Linked List

The update flag in the software process element state is used to update the state of a process element. This command causes the PSL to invalidate any noncoherent copies of the process element that might be cached and to read a new copy from system memory. If the update of the process element is required to be atomic, the process element must be suspended before the update is made (suspend, update, resume).
