A regression has been raised against v23.03-rc3 by Red Hat QE (see tests with FAILED status in the report below).

This regression has been tracked in bz 1196 and fixed with 9e3223adfab7 ("vhost: fix deadlock with no multiqueue").

Test environment:

kernel 5.14
qemu 6.2
dpdk: git://dpdk.org/dpdk

# git log -1
                          commit 9e3223adfab71bc88e9ba67c520b87c529d34a35
                          Author: David Marchand <[email protected]>
                          Date:   Thu Mar 23 15:44:33 2023 +0100
                              vhost: fix deadlock with no multiqueue

This deadlock happens when a guest, that
had virtio ports with multi
queues configured, does not announce the
multi q feature in
SET_FEATURES.
In such a situation, all vq locks are
already taken before calling
free_vq(), which itself takes the lock. As mentioned in the code, in this
situation, the virtio device is not
running yet and no datapath thread is
using the vq. So we can

                              release the lock before calling free_vq().

                              Bugzilla ID: 1196
                              Fixes: 4b02c2673757 ("vhost: annotate

async accesses")
