Subject: netfilter -stable backport request

Hi,

I would like to request a -stable backport for the following patchset that as we speak can be found in pablo's nf-next:

# git://git.kernel.org/pub/scm/linux/kernel/git/pablo/nf-next.git

[PATCH 1/3]
commit 2394ae21e8b652aff0db1c02e946243c1e2f5edb
netfilter: x_tables: pass xt_counters struct instead of packet counter
   
[PATCH 2/3]
commit 18b61e8161cc308cbfd06d2e2c6c0758dfd925ef
netfilter: x_tables: pass xt_counters struct to counter allocator

[PATCH 3/3]
commit 722d6785e3b29a3b9f95c4d77542a1416094786a
netfilter: x_tables: pack percpu counter allocations

Please add this to stable branches : v4.4.x, v4.8.x

The above patchset is fixing a netfilter regression which introduced a performance slowdown in binary arp/ip/ip6tables starting at commit :

#v4.2-rc1
commit 71ae0dff02d756e4d2ca710b79f2ff5390029a5f
netfilter: xtables: use percpu rule counters

Regards,

Eric
