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.
