[SCSI] Generate uevents on certain unit attention codes
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] Signed-off-by: Ewan D. Milne <emilne@redhat.com> Signed-off-by: James Bottomley <JBottomley@Parallels.com>
