However, since the sd_shutdown() function still relies on the manage_system_start_stop flag, a spin-down command is not issued to the disk with command "echo 1 > /sys/block/sdb/device/delete" sd_shutdown() can be called for both system/runtime start stop operations, so utilize the manage_run_time_start_stop flag set in the ata_scsi_dev_config and issue a spin-down command during disk removal when the system is running. This is in addition to when the system is powering off and manage_shutdown flag is set. The manage_system_start_stop flag will still be used for drivers that still set the flag.
