[PATCH 3/4] Introduce XEN scsiback module

[Christoph Hellwig]

Introduces the XEN pvSCSI backend. With pvSCSI it is possible for a XEN domU
to issue SCSI commands to a SCSI LUN assigned to that domU. The SCSI commands
are passed to the pvSCSI backend in a driver domain (usually Dom0) which is
owner of the physical device. This allows e.g. to use SCSI tape drives in a
XEN domU.

This should be written against the generic target core infrastructure
in drivers/target, instead of introducing another simplistic pass
through only SCSI target.

Just to be sure: you mean something like a combined version of
tcm_vhost and virtio_scsi?

It would be roughly equivalent to tcm_vhost. virtio_scsi is the
equivanet of scsifront in Xen.
