patch 'eal: fix return value of lcore role' has been queued to stable release 24.11.3

[Kevin Traynor]

Hi,

FYI, your patch has been queued to stable release 24.11.3

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 07/23/25. 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/4cf7ad1d4188a27e94da43ef59fd07bfce7c2bbe

Thanks.

Kevin

Subject: [PATCH] eal: fix return value of lcore role
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

[ upstream commit 65e03bc2f35109cb33ad4a6e244d5ea90e78fcde ]

Update rte_lcore_has_role() to return false instead of a
negative value for invalid lcore IDs, removing the need
for callers to pre-validate the ID.

Fixes: b0a1502a277c ("eal: make semantics of lcore role function more intuitive")
