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: https://groups.google.com/forum/#!topic/linux.kernel/eRR7AyLE29Y >>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.
