If no, then I may need to organize this series after cdev > series since dev_id is returned to user in cdev series. It shouldn't matter, just go through evey device, check if it is open, check if it has an iommufd_ctx that its the same as the current device and then convert the bind object to a dev_id. Shouldn't matter one bit how iommufd got attached It isn't usable without the cdev series, but it can safely be put ahead of it. Jason
