    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)
