Hi Jason,

I know that this patch is already in Linus's tree but I think this PCI Endpoint
VNTB driver is not going in a correct path. First, Kishon is not convinced with
the way the PCI Endpoint VNTB function driver is written currently. He prefers
the VirtIO approach over the current one [1].

But while the conversation was still going on, the series got merged via NTB
tree without any ACKs from the PCI/PCI_EP maintainers. Also, note that there
was a patch touching the PCI Controller driver as well and that was also not
ACKed [2].

If this trend is going to continue in the coming days, then I'm afraid that NTB
might end up being a backdoor for PCI/PCI_EP patches :(

Thanks,
Mani
