[ Upstream commit 8e48727c26c4d839ff9b4b73d1cae486bea7fe19 ]
Commit aa3998dbeb3a ("ata: libata-scsi: Disable scsi device manage_system_start_stop") enabled libata EH to manage device power mode trasitions for system suspend/resume and removed the flag from ata_scsi_dev_config. 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.
