IrqlKeRaiseLower2 rule (wdm)

The IrqlKeRaiseLower2 rule specifies that drivers use KeLowerIrql to restore the original IRQL raised by a preceding call to KeRaiseIrql or KeRaiseIrqlToDpcLevel.

This rule permits nested calls to KeRaiseIrql, KeRaiseIrqlToDpcLevel and KeLowerIrql.

Driver model: WDM

How to test

At compile time
Run Static Driver Verifier and specify the IrqlKeRaiseLower2 rule. Use the following steps to run an analysis of your code: Prepare your code (use role type declarations). Run Static Driver Verifier. View and analyze the results. For more information, see Using Static Driver Verifier to Find Defects in Drivers.
