[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.

this patch.
