Drivers: hv: vmbus: Remove the lock field from the vmbus_channel struct
scsi: storvsc: Introduce the per-storvsc_device spinlock
Drivers: hv: vmbus: Remove unnecessary channel->lock critical sections (sc_list updaters)
Drivers: hv: vmbus: Use channel_mutex in channel_vp_mapping_show()
Drivers: hv: vmbus: Remove unnecessary channel->lock critical sections (sc_list readers)
Drivers: hv: vmbus: Replace cpumask_test_cpu(, cpu_online_mask) with cpu_online()
