[PATCH] kobject_uevent CONFIG_NET=n fix
lib/lib.a(kobject_uevent.o)(.text+0x25f): In function `kobject_uevent': : undefined reference to `__alloc_skb' lib/lib.a(kobject_uevent.o)(.text+0x2a1): In function `kobject_uevent': : undefined reference to `skb_over_panic' lib/lib.a(kobject_uevent.o)(.text+0x31d): In function `kobject_uevent': : undefined reference to `skb_over_panic' lib/lib.a(kobject_uevent.o)(.text+0x356): In function `kobject_uevent': : undefined reference to `netlink_broadcast' lib/lib.a(kobject_uevent.o)(.init.text+0x9): In function `kobject_uevent_init': : undefined reference to `netlink_kernel_create' make: *** [.tmp_vmlinux1] Error 1 Netlink is unconditionally enabled if CONFIG_NET, so that's OK. kobject_uevent.o is compiled even if !CONFIG_HOTPLUG, which is lazy. Let's compound the sin. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
