Subject: netfilter 00/12: Netfilter fixes/2.6.30 update part II

Hi Dave,

following are a few late netfilter patches and fixes for 2.6.30, containing:

- Eric's patch to use SLAB_DESTROY_BY_RCU in conntrack, which reduces
  the conntrack size and avoids temporarily exceeding the configured
  maximum amount of entries before the RCU threshold kicks in.

- another patch from Eric to factorize the optimized ifname comparisons

- a fix from Eric to use hlist_add_head_rcu in nf_conntrack_set_hashsize()
  to avoid a race condition

- a number of patches from Holger Eitzenberger to perform approximately
  correct allocation (might overshoot by a bit) for ctnetlink event
  messages to avoid reallocation in netlink_trim(). According to some
  benchmarks by Pablo. this increases throughput by about 10% in an
  connection intensive workload.

- a patch fixing a build-failure in the new LED target

- a patch from Francis Dupont to fix an old regression in the *tables
  loop detection. Slightly modified and ported to ip6_tables and
  arp_tables by myself.

Please apply or pull from:

Thanks!
