[09/11] sysctl: Remove the end element in sysctl table arrays

Commit Message

Joel Granados June 21, 2023, 9:48 a.m. UTC

Remove the empty end element from all the arrays that are passed to the
register sysctl calls. In some files this means reducing the explicit
array size by one. Also make sure that we are using the size in
ctl_table_header instead of evaluating the .procname element.

Where's the harm in removing the end elements driver by driver? This is
an unwieldy patch to handle.

The existing indentation is off, but fixing it doesn't really belong in
this patch.

First add size to the register calls, and allow the last one to be
sentinel but do not require the sentinel.

Start removing sentinels, adjusting the size passed in.

Once enough sentinels have been removed, add warning if the final entry
is a sentinel.

Never really remove the check? (But surely you can rework the logic to
not count the number of elements up front, only while iterating.)
