It looks the dependent patch (4d3c5c69191f) is going to miss the v4.20 release.
This is not a big issue, as the dependent patch isn't really important.

Is there any chance for this patch ("Drivers: hv: vmbus: Offload the handling ...") to
go into v4.20?

If yes, I can quickly do a rebase to char-misc's char-misc-linus branch,
because actually the conflict can be very easily fixed. And I can help to fix any
conflict when the dependent patch is backported to v4.20.1.

If no, I think this patch and the dependent patch can both go into v4.21, and
they can be both backported to v4.20.1 in future.

I hope my above reply made me clear. Sorry, I'm not really know how exactly
the releasing procedure works...
