Subject: [PATCH 00/11] VMBus channel interrupt reassignment
Date:   Mon,  6 Apr 2020 02:15:03 +0200

Hi all,

This is a follow-up on the RFC submission [1].  The series introduces
changes in the VMBus drivers to reassign the CPU that a VMbus channel
will interrupt.  This feature can be used for load balancing or other
purposes (e.g. CPU offlining).  The submission integrates feedback in
the RFC to amend the handling of the 'array of channels' (patch #3).

Thanks,
  Andrea

Andrea Parri (Microsoft) (11):
  Drivers: hv: vmbus: Always handle the VMBus messages on CPU0
  Drivers: hv: vmbus: Don't bind the offer&rescind works to a specific
    CPU
  Drivers: hv: vmbus: Replace the per-CPU channel lists with a global
    array of channels
  hv_netvsc: Disable NAPI before closing the VMBus channel
  hv_utils: Always execute the fcopy and vss callbacks in a tasklet
  Drivers: hv: vmbus: Use a spin lock for synchronizing channel
    scheduling vs. channel removal
  PCI: hv: Prepare hv_compose_msi_msg() for the
    VMBus-channel-interrupt-to-vCPU reassignment functionality
  Drivers: hv: vmbus: Remove the unused HV_LOCALIZED channel affinity
    logic
  Drivers: hv: vmbus: Synchronize init_vp_index() vs. CPU hotplug
  Drivers: hv: vmbus: Introduce the CHANNELMSG_MODIFYCHANNEL message
    type
  scsi: storvsc: Re-init stor_chns when a channel interrupt is
    re-assigned
