From bfa858f220ab8c950dd3e1310fee61950d0ecdae Mon Sep 17 00:00:00 2001 From: Thomas Weißschuh Date: Thu, 18 Apr 2024 11:40:08 +0200 Subject: sysctl: treewide: constify ctl_table_header::ctl_table_arg MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit To be able to constify instances of struct ctl_tables it is necessary to remove ways through which non-const versions are exposed from the sysctl core. One of these is the ctl_table_arg member of struct ctl_table_header. Constify this reference as a prerequisite for the full constification of struct ctl_table instances. No functional change.
