Oneline reproducer:

$ stap -e 'probe module("ext3").function("ext3_check_dir_entry")
{print($ext3_filetype_table)}'

semantic error: libdwfl failure (dwfl_getmodules): no error while resolving
probe point module("ext3").function("ext3_check_dir_entry")
Pass 2: analysis failed.  Try again with more '-v' (verbose) options.

Adding some stap -vvv will give (at the end):

The ext3_filetype_table is defined in the same file (fs/ext3/dir.c) as the
function being probed as:

static unsigned char ext3_filetype_table[] = {
        DT_UNKNOWN, DT_REG, DT_DIR, DT_CHR, DT_BLK, DT_FIFO, DT_SOCK, DT_LNK
};
