It looks OK except for a few issues.
The udf_debug macro doesn't need a semicolon after pr_debug(foo); it should be pr_debug(foo) Same for udf_info.
The output prefixes are a mixture of "udf: " and "UDF-fs: "
Some lines are printed with 2 newlines.
I've done the patch below on top of your patch. It should fix up these trivial things.
Perhaps you'll inspect this too.
Convert printks to pr_<level>. Coalesce formats. Rename udf_warning to udf_warn. Add __attribute__((format(printf... verification to udf_warn. Rename udf_error to udf_err. Remove static from udf_err for consistency with other udf_<level> uses. Use printf extension "%pV" in udf_warn and udf_err Remove now unused static char error_buf[1024]. Add no_printk to udf_debug when not #define UDF_DEBUG. Align multiline arguments to open parenthesis. Add newline to message formats where appropriate.
