Recently David Miller and Herbert Xu pointed out that struct net becomes
overbloated and un-maintainable. There are two solutions:
- provide a pointer to a network subsystem definition from struct net.
This costs an additional dereferrence
- place sub-system definition into the structure itself. This will speedup
run-time access at the cost of recompilation timeThe second approach looks better for us. Other sub-systems will follow.

This is the core.
* add the ctl_table_header on the struct net;
* make the unix_sysctl_register and _unregister clone the table;
* moves calls to them into per-net init and exit callbacks;
* move the .data pointer in the proper place.Signed-off-by: Pavel Emelyanov

Unlike previous ones, this patch is useful by its own,
as it decreases the vmlinux size :)But it will be used later, when the per-namespace sysctl
is added.Signed-off-by: Pavel Emelyanov

This will make all the sub-namespaces always use the
default value (10) and leave the tuning via sysctl
to the init namespace only.Per-namespace tuning is coming.

Add the struct net * argument to both of them to use in
the future. Also make the register one return an error code.It is useless right now, but will make the future patches
much simpler.Signed-off-by: Pavel Emelyanov

The semantic effect of insert_at_head is that it would allow new registered
sysctl entries to override existing sysctl entries of the same name. Which is
pain for caching and the proc interface never implemented.I have done an audit and discovered that none of the current users of
register_sysctl care as (excpet for directories) they do not register
duplicate sysctl entries.So this patch simply removes the support for overriding existing entries in
the sys_sysctl interface since no one uses it or cares and it makes future
enhancments harder.Signed-off-by: Eric W. Biederman

Of this type, mostly:
CHECK net/ipv6/netfilter.c

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.Let it rip!
