Yes. so you do:
iommu = open
ioctl(dev1, BIND, iommu)
ioctl(dev2, BIND, iommu)
ioctl(dev3, BIND, iommu)
ioctl(dev4, BIND, iommu)
No need to add a SHARE ioctl.
In my proposal this looks like:
dev1 = open();
ioctl(dev2, SHARE, dev1);
ioctl(dev3, SHARE, dev1);
ioctl(dev4, SHARE, dev1);
So we actually save an ioctl.
The problem with this is that it is assymetric, dev1 is treated
differently from dev[234]. It's an unintuitive API.
