Hi,

FYI, your patch has been queued to stable release 20.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 02/07/21. 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/bluca/dpdk-stable

This queued commit can be viewed at:
https://github.com/bluca/dpdk-stable/commit/02cd8d2c11761f7c8955f93c9c0a55e35254e857

Thanks.

Subject: [PATCH] app/procinfo: fix check on xstats-ids

[ upstream commit 59b981c6f69cb1c705bfb93890ce8cc2a8bcdfb5 ]

'parse_xstats_ids()' return 'int'. The return value is assigned to
'nb_xstats_ids' unsigned value, later negative check on this variable is
wrong.

Adding interim 'int' variable for negative check.

Fixes: 7ac16a3660c0 ("app/proc-info: support xstats by ID and by name")
