A quick tip: inline patches tend to be better than attachments on LKML.
This is because if the mimetype of the attachment is something like
octet/stream then various tools (e.g.
https://lkml.org/lkml/2014/8/26/271 and
https://patchwork.kernel.org/project/LKML/list/?submitter=100981 ) won't
archive/extract the patch...
I rebased your patch on top of the K.Y.'s "Drivers: hv: vmbus: Eliminate
calls to BUG_ON()" patch set (see below). The combination no longer
triggers the bug and it doesn't take too long to boot but the network
interface fails to work (which I believe is .
Rebased vmbus open fixes patch.
