I don't think it's better, the workqueue struct seems large. Maybe having
one wq per IOMMU is a good compromise? As said in my other reply for this
patch, doing so isn't completely straightforward. I'll consider adding an
iommu pointer to the iommu_param struct attached to each device.
Thanks,
Jean
