From 145ce502e44b57c074c72cfdc855557e19026999 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 24 Aug 2010 13:21:08 +0000 Subject: [PATCH] net/sctp: Use pr_fmt and pr_ Change SCTP_DEBUG_PRINTK and SCTP_DEBUG_PRINTK_IPADDR to use do { print } while (0) guards. Add SCTP_DEBUG_PRINTK_CONT to fix errors in log when lines were continued.
