Thanks for reporting this problem.
I have the following patch queued up in the ipvs-next tree
and plan to send a pull request for it later today.
From: "Eric W. Biederman" <ebiederm@xxxxxxxxxxxx>
Subject: [PATCH] ipvs: Don't protect ip_vs_addr_is_unicast with CONFIG_SYSCTL
I arranged the code so that the compiler can remove the unecessary bits
in ip_vs_leave when CONFIG_SYSCTL is unset, and removed an explicit
CONFIG_SYSCTL.
Unfortunately when rebasing my work on top of that of Alex Gartrell I
missed the fact that the newly added function ip_vs_addr_is_unicast was
surrounded by CONFIG_SYSCTL.
So remove the now unnecessary CONFIG_SYSCTL guards around
ip_vs_addr_is_unicast. It is causing build failures today when
CONFIG_SYSCTL is not selected and any self respecting compiler will
notice that sysctl_cache_bypass is always false without CONFIG_SYSCTL
and not include the logic from the function ip_vs_addr_is_unicast in
the compiled code.
