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:

>From what I can tell, I need the original author of a symbol to sign-off on any
patch exporting it. git blame says that the original author is you, so I am
sending this pull request to you for approval.
