This is my take on Maxim's patches.  Mostly I am avoiding the problems with
"scsi/scsi_bus: switch search direction in scsi_device_find" by adding
a pre-realize callback for BusState that checks for the device address
being in use.

This makes it possible to avoid the tricky search for a preexisting device.

Maxim Levitsky (7):
  scsi/scsi_bus: switch search direction in scsi_device_find
  device_core: use drain_call_rcu in in hmp_device_del/qmp_device_add
  device-core: use RCU for list of children of a bus
  device-core: use atomic_set on .realized property
  scsi/scsi_bus: Add scsi_device_get
  virtio-scsi: use scsi_device_get
  scsi/scsi_bus: fix races in REPORT LUNS

Paolo Bonzini (3):
  qdev: add "check if address free" callback for buses
  scsi: switch to bus->check_address
  scsi/scsi-bus: scsi_device_find: don't return unrealized devices
