Hi,

FYI, your patch has been queued to stable release 19.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/11/20. 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/4fa4a861588e9d5edf600903a41baa7df4bb60fb

Thanks.

Luca Boccassi

Subject: [PATCH] examples/performance-thread: fix build with low core count

[ upstream commit 4e3b2d4c76e6249e44b92ffa7c62c031eb23af81 ]

When the value of RTE_MAX_LCORE is small, it results in the
following compilation error.

../examples/performance-thread/l3fwd-thread/main.c:2338:34: error:
iteration 4 invokes undefined behavior
[-Werror=aggressive-loop-optimizations]

Fixes: d48415e1fee3 ("examples/performance-thread: add l3fwd-thread app")
