Only when CONFIG_NET isn't set.

CONFIG_NET=y

Peculiar indeed.

Reading the file, that is
the case. Attached is a patch to remove it.

$ git grep -w -n one net/core/sysctl_net_core.c
net/core/sysctl_net_core.c:26:static int one = 1;
net/core/sysctl_net_core.c:332: .extra2 = &one

Please use grep to augment reading.

grep -w -n one net/core/sysctl_net_core.c
26:static int one = 1;

?

I just don't have the &one.

I am confused now.
