Hm, didn't notice those, sorry.

It seems the condition for the actual export is different than the
Makefile. In ip_conntrack_ftp.c for example the export is done:

#ifdef CONFIG_IP_NF_NAT_NEEDED
EXPORT_SYMBOL(ip_ftp_lock);
#endif

and in Makefile:

ifdef CONFIG_IP_NF_NAT_FTP
        export-objs += ip_conntrack_ftp.o
endif

For some reason these didn't match with my .config, relevant part attached.
