From 9c261b33a9c417ccaf07f41796be278d09d02d49 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Wed, 15 Feb 2012 15:56:43 -0800 Subject: jffs2: Convert most D1/D2 macros to jffs2_dbg D1 and D2 macros are mostly uses to emit debugging messages. Convert the logging uses of D1 & D2 to jffs2_dbg(level, fmt, ...) to be a bit more consistent style with the rest of the kernel. All jffs2_dbg output is now at KERN_DEBUG where some of the previous uses were emitted at various KERN_s.
