X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=4fabcd7118162e36eea5c53e8895ecc13762bef3;p=deliverable%2Flinux.git [NETNS]: Fix allnoconfig compilation error. When CONFIG_NET=no, init_net is unresolved because net_namespace.c is not compiled and the include pull init_net definition. This problem was very similar with the ipc namespace where the kernel can be compiled with SYSV ipc out. This patch fix that defining a macro which simply remove init_net initialization from nsproxy namespace aggregator. Compiled and booted on qemu-i386 with CONFIG_NET=no and CONFIG_NET=yes.
