Merge tag 'constfy-sysctl-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl

Pull sysctl table constification from Joel Granados:
 "All ctl_table declared outside of functions and that remain unmodified
  after initialization are const qualified.

  This prevents unintended modifications to proc_handler function
  pointers by placing them in the .rodata section.

  This is a continuation of the tree-wide effort started a few releases
  ago with the constification of the ctl_table struct arguments in the
  sysctl API done in 78eb4ea25cd5 ("sysctl: treewide: constify the
  ctl_table argument of proc_handlers")"

* tag 'constfy-sysctl-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl:
  treewide: const qualify ctl_tables where applicable
