Koichiro Den fcb32111f0 iommufd: Fix missing update of domains_itree after splitting iopt_area ... commit e7250ab7ca4998fe026f2149805b03e09dc32498 upstream. In iopt_area_split(), if the original iopt_area has filled a domain and is linked to domains_itree, pages_nodes have to be properly reinserted. Otherwise the domains_itree becomes corrupted and we will UAF.
