Subject: [PATCH v10 6/6] mm: Deprecate pasid field
Date: Fri, 27 Oct 2023 08:05:25 +0800	[thread overview]
Message-ID: <20231027000525.1278806-7-tina.zhang@intel.com> (raw)
In-Reply-To: <20231027000525.1278806-1-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.
