[PATCH] md: switch to use pr_debug from <linux/kernel.h>

From: Denis ChengRq
Date: Fri Aug 01 2008 - 02:56:20 EST


the local defined macro dprintk should not be used,

and some of the orignal dprintk use KERN_INFO prefix, but they were actually
debug messages, should use KERN_DEBUG prefix instead, which is pr_debug will do.

Notice: pr_info from kernel.h will always call printk, not according to DEBUG macro,
so cannot be used here, only pr_debug is adaptive to DEBUG.
