From 99e3123e3d72616a829dad6d25aa005ef1ef9b13 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Fri, 30 Dec 2016 08:13:44 -0700 Subject: vfio-mdev: Make mdev_device private and abstract interfaces Abstract access to mdev_device so that we can define which interfaces are public rather than relying on comments in the structure.
