cover target: Initial merge of v4.0.0-rc6 for .38
From: Nicholas Bellinger <[email protected]>
Greetings James,
This following series is based on scsi-misc-2.6.git/master and has been cut against v2.6.37-rc5. It contains three seperate patches to add Target v4.0.0-rc6 and TCM_Loop virtual SCSI LLD for the .38 merge window.
A pullable version of this series is available from:
git://git.kernel.org/pub/scm/linux/kernel/git/nab/scsi-misc-2.6.git merge-for-38
and the individual patches are also available as individual files here:
http://www.kernel.org/pub/linux/kernel/people/nab/TCM-v4-patches-for-v2.6.38/
The full RFC and release history for target core has been included in patch #2.
Best Regards,

PATCH 1/3 scsi: Add missing SPC-4 CDB and MAINTENANCE_[IN,OUT] service action definitions
From: Nicholas Bellinger <[email protected]>
This patch adds a handful of missing CDBs defs that are used by TCM persistent reservation logic in the SPC-4 defined CDB exclusion table for registrations and reservations.
This includes a number of missing MI_* and MO_* prefixed service actions defs for MAINTENANCE_IN and MAINTENANCE_OUT that are mentioned wrt to persistent registration and reservation status for the SCSI Initiator Port.

PATCH 3/3 tcm_loop: Add multi-fabric Linux/SCSI LLD fabric module
In reply to Nicholas A. BellingerFrom: Nicholas Bellinger <[email protected]>
This patch adds the TCM_Loop Linux/SCSI LLD fabric module for accessing TCM device backstores as locally accessable SCSI LUNs in virtual SAS, FC, and iSCSI Target ports using the generic fabric TransportID and Target Port WWN naming handlers from TCM's target_core_fabric_lib.c The TCM_Loop module uses the generic fabric configfs infratructure provided by target_core_fabric_configfs.c and adds a module dependent attribute for the creation/release of the virtual I_T Nexus connected the TCM_Loop Target and Initiator Ports.
TCM_Loop can also be used with the scsi-generic driver so that STGT userspace fabric modules, QEMU-KVM and other hypervisor SCSI passthrough support can access TCM device backstore and control CDB emulation.
