Hi,

FYI, your patch has been queued to stable release 19.11.11

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before December 10th 2021. 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/cpaelzer/dpdk-stable-queue

This queued commit can be viewed at:
https://github.com/cpaelzer/dpdk-stable-queue/commit/43442efcf4a0ba642977e80cd2ec5843e9cb7849

Thanks.

Subject: [PATCH] examples/performance-thread: remove unused hits count

[ upstream commit 130e99db590073dd58da7e5c32dec8c2181527dd ]

Reported by clang 13.
This patch removes the hits variable from the cpu_load_collector function
within the performance thread example app as it is an unused but set
variable.

Bugzilla ID: 881
Fixes: d48415e1fee3 ("examples/performance-thread: add l3fwd-thread app")
