The second patch involves the\nIOMMU programming for guest memory in async vhost.\n\nv4:\n* Fix a format issue.\n\nv3:\n* Move the async_map_status flag to virtio_net structure to avoid\nABI breaking.\n\nv2:\n* Add rte_errno filtering for some devices bound in the kernel driver.\n* Add a flag to check the status of region mapping.\n* Fix one typo.\n\nXuan Ding (2):\n  vfio: allow partially unmapping adjacent memory\n  vhost: enable IOMMU for async vhost\n\n lib/eal/linux/eal_vfio.c | 338 ++++++++++++++++++++++++++-------------\n lib/vhost/vhost.h        |   4 +\n lib/vhost/vhost_user.c   | 112 ++++++++++++-\n 3 files changed, 342 insertions(+), 112 deletions(-)"
