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. The code is taken from the pvSCSI implementation in Xen done by Fujitsu based on Linux kernel 2.6.18. Changes from the original version are: - port to upstream kernel - put all code in just one source file - adapt to Linux style guide - use target core infrastructure instead doing pure pass-through - enable module unloading - support SG-list in grant page(s) - support task abort - remove redundant struct backend - allocate resources dynamically - correct minor error in scsiback_fast_flush_area - free allocated resources in case of error during I/O preparation - remove CDB emulation, now handled by target core infrastructure Signed-off-by: Juergen Gross <jgross@suse.com> Reviewed-by: Nicholas Bellinger <nab@linux-iscsi.org> Signed-off-by: David Vrabel <david.vrabel@citrix.com>
