ipv6: initialize rt6->rt6i_uncached in all pre-allocated dst entries

Initialize rt6->rt6i_uncached on the following pre-allocated dsts: net->ipv6.ip6_null_entry net->ipv6.ip6_prohibit_entry net->ipv6.ip6_blk_hole_entry This is a preparation patch for later commits to be able to distinguish dst entries in uncached list by doing: !list_empty(rt6->rt6i_uncached) Signed-off-by: Wei Wang <[email protected]> Acked-by: Eric Dumazet <[email protected]> Acked-by: Mahesh Bandewar <[email protected]> Signed-off-by: David S.
