Dear Linus, Loading kernel modules off 9p-virtio in a Linux guest causes VM termination because of a page fault in unmapped memory, so I wrote a patch to fix it. Dave Miller initially accepted it, but then rejected it because it calls an unexported symbol from a kernel module, which breaks the build when CONFIG_NET_9P_VIRTIO=m is set in the kernel config:
