Subject: [PATCH 11/16 net-next v2] ipv4: disable IPv4-only sysctls when CONFIG_IPV4=n
Date: Mon, 28 Sep 2026 21:30:07 +0200	[thread overview]
Message-ID: <20260928193046.6698-12-fmancera@suse.de> (raw)
In-Reply-To: <20260928193046.6698-1-fmancera@suse.de>

To avoid noise and unexpected problems, let's hide all the sysctls that
are related to IPv4 only when the kernel is compiled without IPv4
support.
