Subject: [PATCH net-next 0/3] ipv6: fib6_ref conversion to refcount_t

We are chasing use-after-free in IPv6 that could have their origin
in fib6_ref 0 -> 1 transitions.

This patch series should help finding the root causes if these
illegal transitions ever happen.

Eric Dumazet (3):
  ipv6: fib6_info_destroy_rcu() cleanup
  ipv6: broadly use fib6_info_hold() helper
  ipv6: convert fib6_ref to refcount_t
