From 3203558589a597e0a10a66b258fbc5a4a6659ed0 Mon Sep 17 00:00:00 2001 From: Tom Herbert Date: Sun, 28 Aug 2016 14:43:18 -0700 Subject: [PATCH] tcp: Set read_sock and peek_len proto_ops In inet_stream_ops we set read_sock to tcp_read_sock and peek_len to tcp_peek_len (which is just a stub function that calls tcp_inq).
