Hi,

FYI, your patch has been queued to stable release 22.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/27/24. 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/9cdf5aecb261e85cc3ae75eda57a34c7a201b3d5

Thanks.

Luca Boccassi

Subject: [PATCH] mempool: replace GCC pragma with cast

[ upstream commit 23dc03f67279f6ced3dafd2e4c76c1b67a0102dc ]

Building mempool with MSVC generates a warning
because of this pragma (same with clang when debug is enabled).
The issue the pragma was working around can be better solved
by using an additional cast.

Fixes: af75078fece3 ("first public release")
