Subject: [PATCH v2 bpf-next 0/2] BPF iterator for UNIX domain socket.

This patch set adds BPF iterator support for UNIX domain socket.  The first
patch implements it and the second adds a selftest.


Changelog:
  v2:
  - Implement bpf_iter specific seq_ops->stop()
  - Add bpf_iter__unix in bpf_iter.h
  - Move common definitions in selftest to bpf_tracing_net.h
  - Include the code for abstract UNIX domain socket as comment in selftest
  - Use ASSERT_OK_PTR() instead of CHECK()
  - Make ternary operators on single line

  v1:

  bpf: af_unix: Implement BPF iterator for UNIX domain socket.
  selftest/bpf: Implement sample UNIX domain socket iterator program.
