Hi Martin, Since the issue addressed by this patch series concerns a controller bug, please use the SCSI core BLIST mechanism instead of introducing a new sysfs attribute. A sysfs attribute could be misconfigured. BLIST attributes however are set from inside the kernel and hence do not need help from userspace. See e.g. c360652006bb ("scsi: devinfo: BLIST_RETRY_ASC_C1 for Fujitsu ETERNUS"). Thanks, Bart.
