Subject: [RFC PATCH 6/6] mm: Deprecate pasid field
Date: Fri,  7 Jul 2023 09:34:41 +0800	[thread overview]
Message-ID: <20230707013441.365583-7-tina.zhang@intel.com> (raw)
In-Reply-To: <20230707013441.365583-1-tina.zhang@intel.com>

Drop the pasid field, as all the information needed for sva domain
management has been moved to the newly added iommu_mm field.
