Hi,

FYI, your patch has been queued to stable release 22.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/25/24. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the
patch applied to the branch. This will indicate if there was any rebasing
needed to apply to the stable branch. If there were code changes for rebasing
(ie: not only metadata diffs), please double check that the rebase was
correctly done.

Queued patches are on a temporary branch at:
https://github.com/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/8473106d0ca03f5b826fb54cb09f148b41ba8c72

Thanks.

Luca Boccassi

Subject: [PATCH] vdpa: update used flags in used ring relay

[ upstream commit b3f923fe1710e448c073f03aad2c087ffb6c7a5c ]

The vDPA device will work incorrectly if flags such as
VRING_USED_F_NO_NOTIFY are not updated correctly.

Fixes: b13ad2decc83 ("vhost: provide helpers for virtio ring relay")
