Generate a uevent when the following Unit Attention ASC/ASCQ
codes are received:
2A/01 MODE PARAMETERS CHANGED
2A/09 CAPACITY DATA HAS CHANGED
38/07 THIN PROVISIONING SOFT THRESHOLD REACHED
3F/03 INQUIRY DATA HAS CHANGED
3F/0E REPORTED LUNS DATA HAS CHANGED
Log kernel messages when the following Unit Attention ASC/ASCQ
codes are received that are not as specific as those above:
2A/xx PARAMETERS CHANGED
3F/xx TARGET OPERATING CONDITIONS HAVE CHANGED
Added logic to set expecting_lun_change for other LUNs on the target
after REPORTED LUNS DATA HAS CHANGED is received, so that duplicate
uevents are not generated, and clear expecting_lun_change when a
REPORT LUNS command completes, in accordance with the SPC-3
specification regarding reporting of the 3F 0E ASC/ASCQ UA.
[jejb: remove SPC3 test in scsi_report_lun_change and some docbook fixes and
unused variable fix, both reported by Fengguang Wu]
