@Mark -- of the 41 unique patches listed above a goodly portion seem to be already applied.  There seem to be some 20 which are applicable, though I would argue a number of these are code prettyness and not functional:

    Drivers: hv: vmbus: serialize Offer and Rescind offer
    
    Commit 4b2f9abea52a ("staging: hv: convert channel_mgmt.c to not call
    osd_schedule_callback")' was written under an assumption that we never receive
    Rescind offer while we're still processing the initial Offer request. However,
    the issue we fixed in 04a258c162a8 could be caused by this assumption not
    always being true.
    
    In particular, we need to protect against the following:
    1) Receiving a Rescind offer after we do queue_work() for processing an Offer
       request and before we actually enter vmbus_process_offer(). work.func points
       to vmbus_process_offer() at this moment and in vmbus_onoffer_rescind() we do
       another queue_work() without a check so we'll enter vmbus_process_offer()
       twice.
    2) Receiving a Rescind offer after we enter vmbus_process_offer() and
       especially after we set >state = CHANNEL_OPEN_STATE. Many things can go
       wrong in that case, e.g. we can call free_channel() while we're still using
       it.
    
    Implement the required protection by changing work->func at the very end of
    vmbus_process_offer() and checking work->func in vmbus_onoffer_rescind(). In
    case we receive rescind offer during or before vmbus_process_offer() is done
    we set rescind flag to true and we check it at the end of vmbus_process_offer()
    so such offer will not get lost.

    Drivers: hv: rename sc_lock to the more generic lock
    
    sc_lock spinlock in struct vmbus_channel is being used to not only protect the
    sc_list field, e.g. vmbus_open() function uses it to implement test-and-set
    access to the state field. Rename it to the more generic 'lock' and add the
    description.

    Drivers: hv: vmbus: Support a vmbus API for efficiently sending page arrays
    
    Currently, the API for sending a multi-page buffer over VMBUS is limited to
    a maximum pfn array of MAX_MULTIPAGE_BUFFER_COUNT. This limitation is
    not imposed by the host and unnecessarily limits the maximum payload
    that can be sent. Implement an API that does not have this restriction.

    Drivers: hv: hv_balloon: Fix a locking bug in the balloon driver
    
    We support memory hot-add in the Hyper-V balloon driver by hot adding an appropriately
    sized and aligned region and controlling the on-lining of pages within that region
    based on the pages that the host wants us to online. We do this because the
    granularity and alignment requirements in Linux are different from what Windows
    expects. The state to manage the onlining of pages needs to be correctly
    protected. Fix this bug.

    Drivers: hv: hv_balloon: Make adjustments in computing the floor
    
    Make adjustments in computing the balloon floor. The current computation
    of the balloon floor was not appropriate for virtual machines with more than
    10 GB of assigned memory - we would get into situations where the host would
    agressively balloon down the guest and leave the guest in an unusable state.
    This patch fixes the issue by raising the floor.

    storvsc: force discovery of LUNs that may have been removed.
    
    The host asks the guest to scan when a LUN is removed or added.
    The only way a guest can identify the removed LUN is when an I/O is
    attempted on a removed LUN - the SRB status code indicates that the LUN
    is invalid. We currently handle this SRB status and remove the device.
    
    Rather than waiting for an I/O to remove the device, force the discovery of
    LUNs that may have been removed prior to discovering LUNs that may have
    been added.
