iommufd still uses iommu_group_replace_domain() in Joerg's tree. This
could cause compiling issues if this series goes through the iommu tree.

$ git grep  iommu_group_replace_domain
drivers/iommu/iommu-priv.h:int iommu_group_replace_domain(struct 
iommu_group *group,
drivers/iommu/iommu.c: * iommu_group_replace_domain - replace the domain 
that a group is attached to
drivers/iommu/iommu.c:int iommu_group_replace_domain(struct iommu_group 
*group,
drivers/iommu/iommu.c:EXPORT_SYMBOL_NS_GPL(iommu_group_replace_domain, 
"IOMMUFD_INTERNAL");
drivers/iommu/iommu.c: * This is a variant of 
iommu_group_replace_domain(). It allows the caller to
drivers/iommu/iommufd/iommufd_private.h:        return 
iommu_group_replace_domain(idev->igroup->group, hwpt->domain);
