Subject: [PATCH] sysctl: x25: remove unnecessary insert_at_head from
 register_sysctl_table

There has not been much maintenance on sysctl in years, and as a result is
there is a lot to do to allow future interesting work to happen, and being
ambitious I'm trying to do it all at once :)

The patches in this series fall into several general categories.

- Removal of useless attempts to override the standard sysctls

- Registers of sysctl numbers in sysctl.h so someone else does not use
  the magic number and conflict.

- C99 conversions so it becomes possible to change the layout of
  struct ctl_table without breaking everything.

- Removal of useless claims of module ownership, in the proc dir entries

- Removal of sys_sysctl support where people had used conflicting sysctl
  numbers. Trying to break glibc or other applications by changing the
  ABI is not cool.  9 instances of this in the kernel seems a little
  extreme.

- General enhancements when I got the junk I could see out.

This patch:

Since x25 uses unique binary numbers inserting yourself at the head of the
search list for sysctls so you can override already registered sysctls is
pointless.

Subject: [PATCH] sysctl: remove insert_at_head from register_sysctl

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.
