tcp_westwood: fix tcp_westwood_info()
I forgot to update tcp_westwood when changing get_info() behavior, this patch should fix this. Fixes: 64f40ff5bbdb ("tcp: prepare CC get_info() access from getsockopt()") Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Neal Cardwell <ncardwell@google.com> Signed-off-by: David S.
