To be clear the behavior (not all sysctls being visible) is the fix.
The old behavior was buggy.

As for what/when/where I don't recall the details clearly.  That change
happened years ago.  If you want to figure it out you can look at
net/net_sysctl.c:register_net_sysctl() and look into it's history in
git.
