Merge git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next
Pablo Neira Ayuso says:
====================
Netfilter/IPVS updates for net-next
1) Missing dependencies in NFT_BRIDGE_REJECT, from Randy Dunlap.
2) Use atomic_inc_return() instead of atomic_add_return() in IPVS,
from Yejune Deng.
3) Simplify check for overquota in xt_nfacct, from Kaixu Xia.
4) Move nfnl_acct_list away from struct net, from Miao Wang.
5) Pass actual sk in reject actions, from Jan Engelhardt.
6) Add timeout and protoinfo to ctnetlink destroy events,
from Florian Westphal.
7) Four patches to generalize set infrastructure to support
for multiple expressions per set element.

netfilter: nfnl_acct: remove data from struct net
netfilter: Remove unnecessary conversion to bool
ipvs: replace atomic_add_return()
netfilter: nft_reject_bridge: fix build errors due to code movement
