Put this in ll_rw_blk.c:

/*
 * Parse an ascii decimal number into a sector_t.  Return 1 on success
 */
int str_to_sector_t(const char *str, sector_t *sector)
{
	unsigned long long val;
	int ret;

	ret = sscanf(str, "%llu", &val);
	if (ret == 1)
		*sector = val;
	return ret;
}
EXPORT_SYMBOL(str_to_sector_t);
