Comments

The IRQL is set to DISPATCH_LEVEL and the DeviceQueue spin lock is acquired.

If the given DeviceQueueEntry is not in the queue, the IRP either is already being processed, or the IRP has been canceled. In this case, KeRemoveEntryDeviceQueue simply returns FALSE.

The specified DeviceQueue spin lock is released and IRQL is restored to its previous value.

Callers of KeRemoveEntryDeviceQueue must be running at IRQL <= DISPATCH_LEVEL.
