This patchset reimplements sys_sysctl as a compatibility wrapper
around /proc/sys. After which it removes all of the code to all over
the kernel that is used today to implement the binary sysctls.
I am posting this patchset to give everyone a heads up what is in
flight.
I intend to carry all of these patches in my sysctl tree.
If you add new sysctls to other trees please don't set the .ctl_name
or .strategy fields in struct ctl_table, as setting those fields
is unnecessary now and are removed by this patchset.
Last I looked at linux-next is only one new sysctl that is not in
Linus's tree under net/ipv6. David I will send you a patch in a
bit to remove the unnecessary .ctl_name = CTL_UNNUMBERED line so
that linux-next continues to compile when my tree makes it there.

Very nice patches again!
Looking at what you did, I had two ideas how to move on from there,
which may be part of your plans already:
1. Make it possible to build sysctl_binary.c as a loadable module
so you can get a smaller kernel without losing the option to use
binary sysctl altogether. This of course requires a small portion
to remain in the kernel, to provide the actual syscall entry point
and load the module on demand.
2. On top of that, put the same code into glibc so that you don't
even have to load the module when you're running a new glibc version.
Since the binary sysctl ABI is stable (as in stiff and dead), there
should be no need to synchronize any extensions to it betwen kernel
and libc.

I can see how this could make sense from a distribution perspective.

I don't expect we will need to move this to glibc. There are so few
users of sys_sysctl now, that I hardly expect it to be worth it to move
this code out of the kernel.
For me the big problem with sys_sysctl is solved by this patchset.
It no longer constitutes a maintenance burden on the rest of the sysctl
code, and the other sysctl users.
Now the implementation of /proc/sys can be implemented and optimized without
dealing with any sys_sysctl baggage.
All of that said if someone is interested in tweaking sysctl_binary.c to make
it easier to deal with sys_sysctl going away I don't have any problems.
