Message-Id: <970ce5cbebcd204e368cbdb01dedb7ef92c8903d.1351135989.git.joe@perches.com>
Date: Wed, 24 Oct 2012 20:43:43 -0700
From: Joe Perches <joe@...ches.com>
To: Andrew Morton <akpm@...ux-foundation.org>
Cc: Kay Sievers <kay@...y.org>, linux-kernel@...r.kernel.org
Subject: [PATCH V2 08/23] printk: Rename log_<foo> variables and functions
Make these generic names more specific to the printk
subsystem and allow these variables and functions to
become non-static.
Rename log_text to printk_log_text.
Rename log_dict to printk_log_dict.
Rename log_from_idx to printk_log_from_idx.
Rename log_next to printk_log_next.
Rename log_store to printk_log_store.
