From: Neal Cardwell <hidden>
Date: 2020-09-10 19:19:10
Subsystem:
bpf [general] (safe dynamic programs and tools), bpf [networking] (tcx & tc bpf, sock_addr), networking [general], the rest · Maintainers:
Alexei Starovoitov, Daniel Borkmann, Andrii Nakryiko, Eduard Zingerman, Kumar Kartikeya Dwivedi, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds
From: Neal Cardwell <ncardwell@google.com> Now that the previous patches have removed the code that uses the flags argument to _bpf_setsockopt(), we can remove that argument.
