I am a little confusing. The " struct nf_ct_nat_helper ftp_nat ftp_nat" is one new variable, while the original variable "struct nf_ct_nat_helper follow_master_nat" name still is " "nat-follow-master". I couldn't figure about how could this break backward. Do you think the name " ftp_nat " should use " ftp_nat_follow_master"? BTW, how about use nat_helper pointer instead of expect fn? As I mentioned before, it could avoid two assignment. Is it ok?
