Just to clarify sure, the broken configuration is VHOST=y TUN=m, I sent
a fixup patch to forbid that configuration. But both VHOST=y TUN=n and
VHOST=m TUN=n build fine for me on linux-next (commit
af2b07e7e0a9c6bf82ce4d6a77f0412ae54f575b). Randy, could you please
confirm that VHOST=y TUN=m is what you tested, or alternatively make
your .config available to me so I can reproduce the problem?
