> Subject: [PATCH] bitops: mark new symbols as stable
>
> Calling an experimental symbol from an inline helper triggers a warning when
> such code is not compiled with experimental API.
> This can be seen when rte_bitops.h gets (indirectly) included in OVS builds.
>
> On the other hand, rte_clz32, rte_clz64, rte_ctz32, rte_ctz64, rte_popcount32,
> rte_popcount64 are inline helpers for abstracting common bit counting
> functions. This part of the API is unlikely to change.
>
> Mark those symbols as stable.
>
> Fixes: 18898c4d06f9 ("eal: use abstracted bit count functions")
