I believe it better to simply add __FILE__ & __LINE__ to the
macro rather than some other externally specified unique
identifier that adds developer overhead and easily gets stale.
If you go overboard, you could do something like:
#define dev_dbg(dev, format, arg...) \
dev_printk(KERN_DEBUG, dev, DBG_FMT format DBG_ARG, ## arg)
#define dev_err(dev, format, arg...) \
dev_printk(KERN_ERR, dev, PR_FMT format PR_ARG, ## arg)
etc...
and use config variables to control what additional info is printk'ed.
Go overboard without a life preserver and add __TIMESTAMP__ too.
