H A D | vringh.c | f85efa9b Wed Nov 09 04:25:02 CST 2022 Stefano Garzarella <sgarzare@redhat.com> vringh: fix range used in iotlb_translate()
vhost_iotlb_itree_first() requires `start` and `last` parameters to search for a mapping that overlaps the range.
In iotlb_translate() we cyclically call vhost_iotlb_itree_first(), incrementing `addr` by the amount already translated, so rightly we move the `start` parameter passed to vhost_iotlb_itree_first(), but we should hold the `last` parameter constant.
Let's fix it by saving the `last` parameter value before incrementing `addr` in the loop.
