Hi,

FYI, your patch has been queued to stable release 24.11.9

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 10/29/26. 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/d3673cebb7ab67b276a37a226ff9c22ef92c396d

Thanks.

Luca Boccassi

Subject: [PATCH] graph: fix xstats of cloned node

[ upstream commit 32d07e65e0c447442c43b0a2ba4f1000ef50b157 ]

When cloning a node with xstats enabled, xstat_desc entries are copied
into the rte_node_register structure, but the nb_xstats field is not.

As a result, the cloned node reports zero available xstats,
making xstats unusable.

Copy the nb_xstats field when cloning the node so that cloned nodes
preserve the xstats configuration of the original node.

Fixes: 070db97e017b ("graph: support node xstats")
