Subject: [RFT][PATCH v1 4/6] vfio: Rename user_iova of vfio_dma_rw()
Date: Thu, 16 Jun 2022 16:52:10 -0700	[thread overview]
Message-ID: <20220616235212.15185-5-nicolinc@nvidia.com> (raw)
In-Reply-To: <20220616235212.15185-1-nicolinc@nvidia.com>

Following the updated vfio_pin/unpin_pages(), use the simpler "iova".
