This isn't the same.

You should probably just use

#define udf_debug(fmt, ...)						\
	pr_debug("DEBUG %s:%d:%s: " fmt,				\
		 __FILE__, __LINE__, __func__, __VA_ARGS__)

or maybe let dynamic_debug add
__FILE__, __LINE__ and __func__
via the appropriate controls,
so this might be appropriate.

#define udf_debug(fmt, ...)						\
	pr_debug("DEBUG " fmt, __VA_ARGS__)
