1616 * KeWaitForSingleObject() on NDIS timer and event objects, so we
1617 * have to support that as well. Conseqently, our NDIS timer and event
1618 * code has to be closely tied into our ntoskrnl timer and event code,
1630 * - For timers, if the timer has already fired and the timer is in
1632 * timer. Unlike an event, timers get signalled automatically when
1635 * events: KeInitializeTimerEx() lets you initialize a timer as
3404 * a timer or event object, you actually end up with an
3413 * a timer object by simply allocating the memory for a ktimer
