Subject: [PATCH 0/7] vDPA shadow virtqueue iova tree fixes.
Date: Fri, 19 Aug 2022 18:53:50 +0200	[thread overview]
Message-ID: <20220819165357.3591965-1-eperezma@redhat.com> (raw)

Collection of iova tree fixes detected preparing live migration with real
devices and multiqueue.

These cannot be triggered in simple setups (vdpa_sim_net, no display, no
device reset with different features) but it's possible to trigger them with
real devices or if the kernel fails some step like memory mapping / unmapping.

First two patches are already in the list at [1]. Last one is not a fix by
itself but a straightforward merge of the same code.
