Linux-kernel debug printouts?

Question

Is there a better way to debug printouts in the Linux kernel?

Right now littering the code with:

printk(KERN_DBG \"%s:%d - %s() \", __

Use

/* At the top of the file, before any includes */
#define pr_fmt(fmt) KBUILD_MODNAME ": " fmt

#include 

/* in code... */
pr_devel("foobar happened\n");

as a basis (the standard practice). You can then add __FILE__ or __LINE__ to the pr_fmt definition if you need.
