I/O Stack Locations.

Fields

`MajorFunction`	The IRP major function code indicating the type of I/O operation to be performed.
`MinorFunction`	A subfunction code for `MajorFunction`.
`Flags`	Request-type-specific values (see DEVICE_FLAGS).
`Control`
`Parameters`	A union that depends on the major and minor IRP function code values contained in `MajorFunction` and `MinorFunction`.
`DeviceObject`	A pointer to the driver-created `DEVICE_OBJECT` structure representing the target physical, logical, or virtual device for which this driver is to handle the IRP.
`FileObject`	A pointer to a `FILE_OBJECT` structure that represents the file object, if any, that is associated with `DeviceObject` pointer.
`CompletionRoutine`	The following routine is invoked depending on the flags in the above `Flags` field.
`Context`	The following is used to store the address of the context parameter that should be passed to the `CompletionRoutine`.
