From 537fba28928c01b7db1580627450691a4bb0b9b3 Mon Sep 17 00:00:00 2001 From: Dave Peterson Date: Sun, 26 Mar 2006 01:38:40 -0800 Subject: [PATCH] EDAC: printk cleanup This implements the following idea: On Monday 30 January 2006 19:22, Eric W. Biederman wrote: > One piece missing from this conversation is the issue that we need errors > in a uniform format.
