4.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: David Ahern <dsahern@xxxxxxxxx>
[ Upstream commit 80f1a0f4e0cd4bfc8a74fc1c39843a6e7b206b95 ]
Prior to the introduction of fib6_info lwtstate was managed by the dst
code. With fib6_info releasing lwtstate needs to be done when the struct
is freed.
Fixes: 93531c674315 ("net/ipv6: separate handling of FIB entries from dst based routes")
