RE: [PATCH rc 4/8] iommu/vt-d: Update iotlb in nested domain attach

From: Liu, Yi L yi.l.liu@intel.com Sent: Thursday, February 8, 2024 4:23 PM

Should call domain_update_iotlb() to update the has_iotlb_device flag of the domain after attaching device to nested domain. Without it, this flag is not set properly and would result in missing device TLB flush.
