From 87ebdc00eeb474615496d5f10eed46709e25c707 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Wed, 27 Feb 2013 17:03:16 -0800 Subject: [PATCH] fs/proc: clean up printks - use pr_foo() throughout - remove a couple of duplicated KERN_WARNINGs, via WARN(KERN_WARNING "...") - nuke a few warnings which I've never seen happen, ever.
