> Changes in v2:
> * rebase on top of net-next
> * currently by default refcount_t = atomic_t (*) and uses all
> atomic standard operations unless CONFIG_REFCOUNT_FULL is enabled.
> This is a compromise for the systems that are critical on
> performance (such as net) and cannot accept even slight delay
> on the refcounter operations.
>
> This series, for ipv4/ipv6 network components, replaces atomic_t reference
> counters with the new refcount_t type and API (see include/linux/refcount.h).
> By doing this we prevent intentional or accidental
> underflows or overflows that can led to use-after-free vulnerabilities.
>
> The patches are fully independent and can be cherry-picked separately.
> In order to try with refcount functionality enabled in run-time,
> CONFIG_REFCOUNT_FULL must be enabled.

Series applied, thanks.
