From af714b6b565e59a86ab2dc48f56b5a87337f093a Mon Sep 17 00:00:00 2001 From: Arjan van de Ven Date: Thu, 22 Oct 2009 21:37:56 -0700 Subject: [PATCH] net: use WARN() for the WARN_ON in commit 3ee3eb2ac1687 Commit 3ee3eb2ac1687 (tcp: Try to catch MSG_PEEK bug) added a printk() to the WARN_ON() that's in tcp.c. This patch changes this combination to WARN(); the advantage of WARN() is that the printk message shows up inside the message, so that kerneloops.org will collect the message. In addition, this gets rid of an extra if() statement. Signed-off-by: Arjan van de Ven Signed-off-by: David S.
