Subject: [PATCH v2 5/5] mm: Deprecate pasid field
Date: Sun, 27 Aug 2023 16:44:01 +0800 [thread overview]
Message-ID: <20230827084401.819852-6-tina.zhang@intel.com> (raw)
In-Reply-To: <20230827084401.819852-1-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.
