While going through the tree trying to document all of our
net.inet6 sysctls, I noticed that net.inet6.ip6.rr_prune is defined,
but not actually used anywhere in the stack:
netinet6/ip6_var.h:VNET_DECLARE(int, ip6_rr_prune); /* router
renumbering prefix
netinet6/ip6_var.h:#define V_ip6_rr_prune VNET(ip6_rr_prune)
netinet6/in6_proto.c:VNET_DEFINE(int, ip6_rr_prune) = 5; /* router
renumbering prefix
netinet6/in6_proto.c:SYSCTL_VNET_INT(_net_inet6_ip6, IPV6CTL_RR_PRUNE,
rr_prune, CTLFLAG_RW,
netinet6/in6_proto.c: &VNET_NAME(ip6_rr_prune), 0,
The knob was declared in r181803 and shuffled around a few times,
but isn't in use anywhere (either then or now).
Should I send out a PR to remove it (or am I missing some context)?
Thanks,
-Garrett
