Hi all,
This series introduces changes in the VMBus drivers to reassign (at
runtime) the CPU that a VMbus channel will interrupt. This feature
can be used for load balancing or other purposes, e.g. to offline a
given vCPU (vCPUs with no interrupts assigned can be taken offline).
Thanks,
Andrea

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
