patch 'app/compress-perf: optimize operations pool allocation' has been queued to stable release 21.11.1

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 21.11.1

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/14/22. 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/kevintraynor/dpdk-stable

This queued commit can be viewed at:
https://github.com/kevintraynor/dpdk-stable/commit/0fc99dc715acfcaea4c46f9196689aaac600ba6a

Thanks.

Kevin

Subject: [PATCH] app/compress-perf: optimize operations pool allocation

[ upstream commit 68d3287f4ef43318728e4a134b7aa33d5c52b12d ]

An array of the size of total operations needed for the de/compression is
reserved for ops while enqueueing, although only first burst_size entries
of the array are used.

Reduce the size of the array allocated.

Fixes: b68a82425da4 ("app/compress-perf: add performance measurement")
