问谁拥有WDFREQUEST中的WDFMEMORY？

EN

// Create request
WDFREQUEST request;
status = WdfRequestCreate(WDF_NO_OBJECT_ATTRIBUTES, target, &request);
if (!NT_SUCCESS(status)) {
    goto exit;
}

// Allocate buffer for request
WDFMEMORY inputMemory;
status = WdfMemoryCreate(WDF_NO_OBJECT_ATTRIBUTES, PagedPool, 0, 1024, &inputMemory, NULL);
if (!NT_SUCCESS(status)) {
    goto exit;
}

// Assign input buffer to request
status = WdfIoTargetFormatRequestForIoctl(target, request, IOCTL_FOO, inputMemory, NULL, NULL, NULL);
if (!NT_SUCCESS(status)) {
    goto exit;
}

// Asynchronously send the ioctl request
WdfRequestSetCompletionRoutine(request, MyCompletionRoutine, NULL);
if (!WdfRequestSend(request, target, NULL)) {
    status = WdfRequestGetStatus(request);
    goto exit;
}
