Maybe I'm missing something, but how come this patch even made its way
into 4.14.y? It's part of a series to RCU-ify IPv6 FIB lookup that went
into 4.15.
Anyway, the mentioned bug was already fixed by commit 951f788a80ff
("ipv6: fix a BUG in rt6_get_pcpu_route()") when the code was still in
net-next.
