[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/05/25. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/f25ac9297da16ea4f5f193b1977f192888f7a4c4

Thanks.

Kevin

Subject: [PATCH] vhost: fix virtqueue info init in VDUSE vring setup

[ upstream commit db91578981c6869d4ee476347141c0fccd1d6146 ]

Initialize vduse_vq_info structure to zero to avoid using
uninitialized memory when setting up VDUSE virtual rings.
This ensures all fields start with known values.

Fixes: a9120db8b98b ("vhost: add VDUSE device startup")
