Flags_Irql

Flags_Irql rule (ndis)

The Flags_Irql rule specifies that KeGetCurrentIrql must not be called within callback functions that have a dispatch level flag parameter that indicates the current IRQL.

The correct use of the dispatch level flag can help you avoid unnecessary attempts to set the IRQL. For more information about how to use this flag, see Dispatch IRQL Tracking.
