I prefer removing all __FILE__, __FUNCTION__, __LINE__ uses
from printks and defining something that modifies pr_<level>.

Something like:

#define PR_FILE
#define PR_FUNCTION
#define PR_LINE

#if    defined PR_FILE &&  defined PR_FUNCTION &&  defined PR_LINE
#define PR_FMT "(%s:%s:%u) "
#define PR_ARG , __FILE__ , __FUNCTION__ , __LINE__ 
#elif  defined PR_FILE &&  defined PR_FUNCTION && !defined PR_LINE
#define PR_FMT "(%s:%s) "
#define PR_ARG , __FILE__ , __FUNCTION__ 
#elif  defined PR_FILE && !defined PR_FUNCTION &&  defined PR_LINE
#define PR_FMT "(%s:%u) "
#define PR_ARG , __FILE__ , __LINE__ 
#elif  defined PR_FILE && !defined PR_FUNCTION && !defined PR_LINE
#define PR_FMT "(%s) "
#define PR_ARG , __FILE__ 
#elif !defined PR_FILE &&  defined PR_FUNCTION &&  defined PR_LINE
#define PR_FMT "(%s:%u) "
#define PR_ARG , __FUNCTION__ , __LINE__ 
#elif !defined PR_FILE &&  defined PR_FUNCTION && !defined PR_LINE
#define PR_FMT "(%s) "
#define PR_ARG , __FUNCTION__ 
#elif !defined PR_FILE && !defined PR_FUNCTION && defined PR_LINE
#define PR_FMT "(%u) "
#define PR_ARG , __LINE__ 
#else
#define PR_FMT
#define PR_ARG
#endif

#define pr_info(fmt, arg) printk(KERN_INFO PR_FMT fmt PR_ARG, ##arg)
