Hi,

FYI, your patch has been queued to stable release 24.11.7

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 06/13/26. 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/20d0356be03d161b0f13a92244ec77515f9a3f2f

Thanks.

Luca Boccassi

Subject: [PATCH] net/hinic: fix mutexes for multi-process

[ upstream commit 4a0cb075206c80559c12726fa5a61a670fbe92a3 ]

The hinic driver supports secondary processes. Mutexes in structures
allocated in shared memory must be initialized with
PTHREAD_PROCESS_SHARED. All callers of hinic_mutex_init() pass NULL
as the attribute argument, so route it through the EAL helper and
drop the unused parameter handling.

Bugzilla ID: 662
Fixes: ae865766b334 ("net/hinic: replace spinlock with mutex")
