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/0de12cad1bc1661272a25f59a8767a8c38743843

Thanks.

Luca Boccassi

Subject: [PATCH] event/opdl: fix compile-time check

[ upstream commit 3b342be177979eeaf020b75a2c5ec21bcdbc07ea ]

RTE_BUILD_BUG_ON() was being used with a non-constant value.
The inline function rte_is_power_of_2() is not constant since
inline expansion happens later in the compile process.
Replace it with the macro which will be constant.

Fixes: 4236ce9bf5bf ("event/opdl: add OPDL ring infrastructure library")
