Subject: [Patch 3/3] vfio/common: Rename VFIOGuestIOMMU::iommu into ::iommu_mr
Date: Mon,  2 May 2022 02:42:23 -0700	[thread overview]
Message-ID: <20220502094223.36384-4-yi.l.liu@intel.com> (raw)
In-Reply-To: <20220502094223.36384-1-yi.l.liu@intel.com>

Rename VFIOGuestIOMMU iommu field into iommu_mr. Then it becomes clearer
it is an IOMMU memory region.

no functional change intended
