DoubleCompletion rule (kmdf)
The DoubleCompletion rule specifies that drivers must not complete an I/O request twice. The following methods should not be called twice in a row for the same request: WdfRequestComplete, WdfRequestCompleteWithInformation, WdfRequestCompleteWithPriorityBoost.
The difference between this rule and the DoubleCompletionLocal rule is that the DoubleCompletionLocal rule is only performed within the default I/O queue callback functions.
