freebsd camp is using linker hack for them.
- in sys/netinet/ip_icmp.c, declare leaf node as:
SYSCTL_INT(_net_inet_icmp, OID_AUTO, log_redirect, CTLFLAG_RW,
&log_redirect, 0, "");
- it will put certain symbol into the kernel, like:
>c025c60c r __set_sysctl__net_inet_icmp_sym_sysctl___net_inet_icmp_log_redirect
- sys/sysctl.h has #define SYSCTL_INT() foobaa.
Though I think I like the idea of having sysctl table definition in
single place, I hate the way it is implemented in freebsd (if
you forget to include sys/sysctl.h you will be in trouble which is
VERY hard to track down). I prefer the current netbsd way than
