Yes, if you make virtio-pci modular, it won't load unless
you have this commit:

commit 5ff16110c637726111662c1df41afd9df7ef36bd
Author: Herbert Xu <herbert@...dor.apana.org.au>
Date:   Wed Dec 17 00:54:03 2014 +0200

    virtio_pci: restore module attributes

So v3.19-rc1 is OK, but net-next/master is not.

Dave - will v3.19-rc1 be merged into net-next?
Could you please confirm?
