[PATCH 0/2] scsi/scsi_debug: Add missing scsi.h defs and XDWRITEREAD_32 support

[Nicholas A. Bellinger]

From: Nicholas Bellinger <nab@linux-iscsi.org>

Hi Doug and James,

Attached are two patches for Linux/SCSI that I ended up needing to allow the
simple XDWRITEREAD_32 passthrough into TCM/pSCSI -> struct request -> SCSI Midlayer
in recent lio-core-2.6.git/lio-4.0 commits.

The first adds some missing SPC-4 CDB and MAINTENANCE_[IN,OUT] +
VARIABLE_LENGTH_CMD service actions to include/scsi/scsi.h.  These
are used by TCM Core code and pieces of this patch have been posted
here for the RFC before:

http://marc.info/?l=linux-scsi&m=128316041105964&w=2

The second adds XDWRITEREAD_32 emulation to scsi_debug, which
is pretty quite simple because everything we need is already
handled by XDWRITEREAD_10.  8-)

This has been tested using 'sgv4_xdwriteread -e' with TCM_Loop ->
TCM/pSCSI -> scsi_debug 32-byte BIDI-COMMAND CDB passthrough on
v2.6.36-rc4.

Thanks!
