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/48ff843561d5379cf582a2b887f72a154f69d9f5

Thanks.

Luca Boccassi

Subject: [PATCH] bitops: fix build with GCC 17

[ upstream commit 254ee546271c8cfc8a764ee3209c44e58875234c ]

Newer GCC warns when a non-boolean constant is an operand of &&
(-Wconstant-logical-operand), which trips whenever RTE_IS_POWER_OF_2
is used in a static_assert with a power-of-two literal.
Make the zero check explicit.

Fixes: 7c872b96983a ("hash: validate hash bucket entries while compiling")
