    Lamparter.

 2) Fix route use after free, from Eric Dumazet.

 3) Fix regression in reuseaddr handling, from Josef Bacik.

 4) Assert the size of control messages in compat handling since we copy
    it in from userspace twice. From Meng Xu.

 5) SMC layer bug fixes (missing RCU locking, bad refcounting, etc.)
    from Ursula Braun.

 6) Fix races in AF_PACKET fanout handling, from Willem de Bruijn.

 7) Don't use ARRAY_SIZE on spinlock array which might have zero
    entries, from Geert Uytterhoeven.
