Damien Le Moal 24eca2dce0 scsi: sd: Introduce manage_shutdown device flag ... Commit aa3998dbeb ("ata: libata-scsi: Disable scsi device manage_system_start_stop") change setting the manage_system_start_stop flag to false for libata managed disks to enable libata internal management of disk suspend/resume. However, a side effect of this change is that on system shutdown, disks are no longer being stopped (set to standby mode with the heads unloaded). While this is not a critical issue, this unclean shutdown is not recommended and shows up with increased smart counters (e.g. the unexpected power loss counter "Unexpect_Power_Loss_Ct"). Instead of defining a shutdown driver method for all ATA adapter drivers (not all of them define that operation), this patch resolves this issue by further refining the sd driver start/stop control of disks using the new flag manage_shutdown. If this new flag is set to true by a low level driver, the function sd_shutdown() will issue a START STOP UNIT command with the start argument set to 0 when a disk needs to be powered off (suspended) on system power off, that is, when system_state is equal to SYSTEM_POWER_OFF. Similarly to the other manage_xxx flags, the new manage_shutdown flag is exposed through sysfs as a read-write device attribute. To avoid any confusion between manage_shutdown and manage_system_start_stop, the comments describing these flags in include/scsi/scsi.h are also improved.
