Takes as is, this conflicts with cleanup patches by Asias in vhost-next that I was going to send to Linus for 3.11. Merging new target code for 3.11 and vhost code for 3.12 helps keep the dependencies simple, so I'm all for it. > > --nab -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
