Subject: [NET]: Make AF_UNIX per network namespace safe [v2]
X-Git-Tag: v2.6.25-rc1~1162^2~1389

[NET]: Make AF_UNIX per network namespace safe [v2]

Because of the global nature of garbage collection, and because of the
cost of per namespace hash tables unix_socket_table has been kept
global.  With a filter added on lookups so we don't see sockets from
the wrong namespace.

Currently I don't fold the namesapce into the hash so multiple
namespaces using the same socket name will be guaranteed a hash
collision.

Changes from v1:
- fixed unix_seq_open
