	I see why I missed this error. There is some
inefficiency in the build process. Once, I tested the
netns init problems with CONFIG_IP_VS=y, later switched back
to CONFIG_IP_VS=m without 'make clean' but the ip_vs.ko
is not considered, I still get ip_vs as builtin, not as
module:

# cat net/netfilter/ipvs/modules.builtin
kernel/net/netfilter/ipvs/ip_vs.ko

	Is only 'make clean' a solution for such
y->m change?

Regards
