Hi,

FYI, your patch has been queued to stable release 22.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 03/09/24. 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/3dba8ba7977ddfb009263d300cf04c016c81231b

Thanks.

Luca Boccassi

[ upstream commit f805f70bc5511cd98a34fa2f8f7bd7a3e4cd8aa3 ]

gcc [1] generates warning [2] about calloc usage, because calloc
parameter order is wrong, fixing it by replacing parameters.

[1]
gcc (GCC) 14.0.1 20240124 (experimental)

[2]
Compiling C object .../common_mlx5_mlx5_common_mr.c.o
.../mlx5/mlx5_common_mr.c: In function ‘mlx5_mempool_get_chunks’:
.../common/mlx5/mlx5_common_mr.c:1384:29:
  warning: ‘calloc’ sizes specified with ‘sizeof’ in the earlier
  argument and not in the later argument [-Wcalloc-transposed-args]
 1384 |         *out = calloc(sizeof(**out), n);
      |                             ^
