patch 'examples/performance-thread: remove unused hits count' has been queued to stable release 20.11.4

[Xueming Li]

Hi,

FYI, your patch has been queued to stable release 20.11.4

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 11/30/21. 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/steevenlee/dpdk

This queued commit can be viewed at:
https://github.com/steevenlee/dpdk/commit/0d266c9fe9d9ea2cba73631e12f8c8b53cd3d8f1

Thanks.

Subject: [PATCH] examples/performance-thread: remove unused hits count
Cc: Xueming Li <xuemingl at nvidia.com>

[ 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")
