The series was split from my larger series sysctl-const series [0].
It only focusses on the proc_handlers but is an important step to be
able to move all static definitions of ctl_table into .rodata.

Split this per subsystem, please.

I've done a few painful API transitions before, and I don't think the
complexity of these changes needs a per-subsystem constification pass. I
think this series is the right approach, but that patch 11 will need
coordination with Linus. We regularly do system-wide prototype changes
like this right at the end of the merge window before -rc1 comes out.

That sounds good.

The requirements are pretty simple: it needs to be a obvious changes
(this certainly is) and as close to 100% mechanical as possible. I think
patch 11 easily qualifies. Linus should be able to run the same Coccinelle
script and get nearly the same results, etc. And all the other changes
need to have landed. This change also has no "silent failure" conditions:
anything mismatched will immediately stand out.

Unfortunately coccinelle alone is not sufficient, as some helpers with
different prototypes are called by handlers and themselves are calling
handler and therefore need to change in the same commit.
But if I add a diff for those on top of the coccinelle script to the
changelog it should be obvious.

Judging by Kees' comment on "100% mechanical", it might be better just
having the diff and have Linus apply than rather than two step process?
Have not these types of PRs, so am interested in what folks think.

I tried to soften it a little with my "*close* to 100%" modifier, and
I think that patch basically matched that requirement, and where it had
manual changes it was detailed in the commit log. I only split out the
seccomp part because it could actually stand alone.

So yeah, let's get the last of the subsystem specific stuff landed after
-rc1, and it should be possible to finish it all up for 6.11. Yay! :)

-Kees
