Subject: [PATCH v1 net-next 0/6] af_unix: Introduce per-netns socket hash table.

This series replaces unix_socket_table with a per-netns hash table and
reduce lock contention.

Note the 3rd-6th patches can be a single patch, but for ease of review,
they are split into small changes without breakage.

Kuniyuki Iwashima (6):
  af_unix: Clean up some sock_net() uses.
  af_unix: Include the whole hash table size in UNIX_HASH_SIZE.
  af_unix: Define a per-netns hash table.
  af_unix: Acquire/Release per-netns hash table's locks.
  af_unix: Put a socket into a per-netns hash table.
  af_unix: Remove unix_table_locks.
