Subject: [PATCH 0/8] Drivers: hv: vmbus: Miscellaneous cleanups

Hi all,

I went back to my "cleanup list" recently and I wrote these patches:
here you can find, among other things,

  1) the removal of the fields 'target_vp' and 'numa_node' from the
     channel data structure, as suggested by Michael back in May;

  2) various cleanups for channel->lock, which is actually *removed
     by the end of this series!  ;-)

I'm sure there is room for further "cleanups",  ;-) but let me check
if these (relatively small) changes make sense first...

Thanks,
  Andrea
