As mentionned by Robin, there are series planning to use
DOMAIN_ATTR_NESTING to get info about the nested caps of the iommu (ARM

[Patch v8 00/10] vfio: expose virtual Shared Virtual Addressing to VMs
patches 1, 2, 3

Is the plan to introduce a new domain_get_nesting_info ops then?

The plan as usual would be to add it the series adding that support.
Not sure what the merge plans are - if the series is ready to be
merged I could rebase on top of it, otherwise that series will need
to add the method.
