This series, for ipv4/ipv6 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. If there are no objections to the patches, please merge them via respective trees.
