====================
Netfilter/IPVS updates for net-next

The following patchset contains Netfilter/IPVS updates for your net-next
tree, they are:

1) Speed up table replacement on busy systems with large tables
   (and many cores) in x_tables. Now xt_replace_table() synchronizes by
   itself by waiting until all cpus had an even seqcount and we use no
   use seqlock when fetching old counters, from Florian Westphal.

2) Add nf_l4proto_log_invalid() and nf_ct_l4proto_log_invalid() to speed
   up packet processing in the fast path when logging is not enabled, from
   Florian Westphal.

3) Precompute masked address from configuration plane in xt_connlimit,
   from Florian.

4) Don't use explicit size for set selection if performance set policy
   is selected.

5) Allow to get elements from an existing set in nf_tables.

6) Fix incorrect check in nft_hash_deactivate(), from Florian.

7) Cache netlink attribute size result in l4proto->nla_size, from
   Florian.

8) Handle NFPROTO_INET in nf_ct_netns_get() from conntrack core.

9) Use power efficient workqueue in conntrack garbage collector, from
   Vincent Guittot.

10) Remove unnecessary parameter, in conntrack l4proto functions, also
    from Florian.

11) Constify struct nf_conntrack_l3proto definitions, from Florian.

12) Remove all typedefs in nf_conntrack_h323 via coccinelle semantic
    patch, from Harsha Sharma.

13) Don't store address in the rbtree nodes in xt_connlimit, they are
    never used, from Florian.

14) Fix out of bound access in the conntrack h323 helper, patch from
    Eric Sesterhenn.

15) Print symbols for the address returned with %pS in IPVS, from
    Helge Deller.

16) Proc output should only display its own netns in IPVS, from
    KUWAZAWA Takuya.

17) Small clean up in size_entry_mwt(), from Colin Ian King.

18) Use test_and_clear_bit from nf_nat_proto_clean() instead of separated
    non-atomic test and then clear bit, from Florian Westphal.

19) Consolidate prefix length maps in ipset, from Aaron Conole.

20) Fix sparse warnings in ipset, from Jozsef Kadlecsik.

21) Simplify list_set_memsize(), from simran singhal.
