Merge branch 'ipv4-namespacify-ipv4-address-hash-table'
Kuniyuki Iwashima says:
====================
ipv4: Namespacify IPv4 address hash table.
This is a prep of per-net RTNL conversion for RTM_(NEW|DEL|SET)ADDR.
Currently, each IPv4 address is linked to the global hash table, and
this needs to be protected by another global lock or namespacified to
support per-net RTNL.
Adding a global lock will cause deadlock in the rtnetlink path and GC,
rtnetlink check_lifetime
|- rtnl_net_lock(net) |- acquire the global lock
|- acquire the global lock |- check ifa's netns
`- put ifa into hash table `- rtnl_net_lock(net)
so we need to namespacify the hash table.
The IPv6 one is already namespacified, let's follow that.
