From f32138319ca6541e65f95f8e17c9cc88ac1baf94 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Tue, 15 May 2012 14:11:53 +0000 Subject: [PATCH] net: ipv6: Standardize prefixes for message logging Add #define pr_fmt(fmt) as appropriate. Add "IPv6: " to appropriate files. Convert printk(KERN_ to pr_ (but not KERN_DEBUG). Standardize on "%s: " not "%s(): " when emitting __func__. Use "%s: ", __func__ instead of embedding function name. Coalesce formats, align arguments. ADDRCONF output is now prefixed with "IPv6: " Signed-off-by: Joe Perches Signed-off-by: David S.
