Series applied, thanks
This patch series contains cleanups to conntrack and related users such as ovs and act_ct. First patch converts conntrack reference counting to refcount_t api. Second patch gets rid of ip_ct_attach hook, we can use existing nf_ct_hook for this. Third patch constifies a couple of structures that don't need to be writeable. Last two patches splits nf_ct_put and nf_conntrack_put. These functions still do the same thing, but now only nf_conntrack_put uses the nf_ct_hook indirection, nf_ct_put uses a direct call. Virtually all places should use nf_ct_put -- only core kernel code needs to use the indirection. Before this change, nf_ct_put was merely an alias for nf_conntrack_put so even conntrack itself did additional indirection. Florian Westphal (5): netfilter: conntrack: convert to refcount_t api netfilter: core: move ip_ct_attach indirection to struct nf_ct_hook netfilter: make function op structures const netfilter: conntrack: avoid useless indirection during conntrack destruction net: prefer nf_ct_put instead of nf_conntrack_put include/linux/netfilter.h | 10 ++-- include/linux/netfilter/nf_conntrack_common.h | 10 ++-- include/net/netfilter/nf_conntrack.h | 8 ++- net/netfilter/core.c | 29 +++++------ net/netfilter/nf_conntrack_core.c | 50 +++++++++---------- net/netfilter/nf_conntrack_expect.c | 4 +- net/netfilter/nf_conntrack_netlink.c | 10 ++-- net/netfilter/nf_conntrack_standalone.c | 4 +- net/netfilter/nf_flow_table_core.c | 2 +- net/netfilter/nf_nat_core.c | 2 +- net/netfilter/nf_synproxy_core.c | 1 - net/netfilter/nfnetlink_queue.c | 8 +-- net/netfilter/nft_ct.c | 4 +- net/netfilter/xt_CT.c | 3 +- net/openvswitch/conntrack.c | 15 ++++-- net/sched/act_ct.c | 7 ++- 16 files changed, 84 insertions(+), 83 deletions(-)
