I thought you were telling me that you were missing in the 00/00 :). I

I see now that just saying "this is part of the effort to remove the
last empty element", does not put all this in to context. I spent some
time looking into the lists for some context and I think Luis summarizes
it quite nicely here
https://lore.kernel.org/all/20230302204612.782387-1-mcgrof@xxxxxxxxxx/.

As I read it removing the last empty element from the ctl_table arrays
is part of a greater effort to remove the clutter in kernel/sysctl.c.

Here is one that actually hints at the ARRAY_SIZE solution.

Here are some other threads that mention the overall effort:

I will add a better motivational part to V2

Thx for the feedback
