From f545a38f74584cc7424cb74f792a00c6d2589485 Mon Sep 17 00:00:00 2001 From: Eric Dumazet Date: Sun, 22 Apr 2012 23:34:26 +0000 Subject: net: add a limit parameter to sk_add_backlog() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit sk_add_backlog() & sk_rcvqueues_full() hard coded sk_rcvbuf as the memory limit. We need to make this limit a parameter for TCP use. No functional change expected in this patch, all callers still using the old sk_rcvbuf limit.
