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.
