Subject: [PATCH v2 09/18] sysctl: treewide: constify ctl_table_root::set_ownership
Date: Mon, 04 Dec 2023 08:52:22 +0100	[thread overview]
Message-ID: <20231204-const-sysctl-v2-9-7a5060b11447@weissschuh.net> (raw)
In-Reply-To: <20231204-const-sysctl-v2-0-7a5060b11447@weissschuh.net>

In a future commit the sysctl core will only use
"const struct ctl_table". As a preparation for that adapt the
set_ownership callbacks.
