RE: [PATCH v6 2/4] iommufd: Add iommufd_access_replace() API

From: Nicolin Chen nicolinc@nvidia.com Sent: Tuesday, March 28, 2023 2:05 AM

Extract all common procedure, between the iommufd_access_attach() API and the new iommufd_access_replace() API, to an iommufd_access_change_pt() helper.

Add iommufd_access_replace() function for VFIO emulated pathway to use.
