From: Simon Horman <horms@xxxxxxxxxxxx>
Much of ip_vs_leave() is unnecessary if CONFIG_SYSCTL is undefined.
I tried an approach of breaking the now #ifdef'ed portions out
into a separate function. However this appeared to grow the
compiled code on x86_64 by about 200 bytes in the case where
CONFIG_SYSCTL is defined. So I have gone with the simpler though
less elegant #ifdef'ed solution for now.
