Would it be possible to pick up two patches. I could prune this down to two. The two I want you to
pick up are (in the order of importance):
[PATCH 1/6] Drivers: hv: vmbus: Perform device register in the per-channel work element
[PATCH 2/6] Drivers: hv: hv_balloon: keep locks balanced on add_memory() failure
If you could pickup an additional patch that would be:
[PATCH 6/6] Drivers: hv: vmbus: Fix a bug in rescind processing in vmbus_close_internal()
The first one is the most important one and if you can only pickup one, the first one is the one I want you to pick up.
The third one fixes a memory leak issue that occurs only under
certain conditions. We may have to revert more patches than applying the two patches that
would fix the most important issues.
Let me know if you want me to resend the ones that you can apply.
