Subject: [PATCH 0/2] [Target_Core_Mod]: Add support for UNIT_ATTENTION with
	SPC-3 PR

Greetings all,

This patch adds support for SAM4/SPC4 compliant UNIT_ATTENTION with ua_intlck_ctrl 
control mode page value 00b, 10b and 11b.  The default has been set to 0 in configfs,
which is to clear the UNIT ATTENTION with a CHECK_CONDITION+Sense data with a
corresponding ASC+ASCQ.  Currently, Linux/SCSI midlayer clients require a manual sg_request
to clear the UNIT ATTENTION with a REQUEST_SENSE for modes 10b and 11b.  These values can be
changed (without active $FABRIC_MOD target ports) for a given target_core_mod storage object
with ConfigFS via /sys/kernel/config/target/core/$HBA/$DEV/attrib/emulated_ua_intlck_ctrl.
The echoed values for the attribute into ConfigFS are 0, 1, and 2 respectively for the
interlock codes 00b, 10b, and 11b.

These patches are made against lio-core-2.6.git/master and tested on
v2.6.29 x86 32-bit HVM using sg_persist from sg3_utils.  The lio-core-2.6.git tree
can be found at:
