Comments

KeInitializeDeviceQueue initializes the specified device queue and sets its state to not busy.

A driver should call KeInitializeDeviceQueue from its AddDevice routine after creating the device object for the associated device. Storage for the device queue object must be resident: in the device extension of a driver-created device object, in the controller extension of a driver-created controller object, or in nonpaged pool allocated by the caller.
