This patch removes a legacy struct se_hba->hba_dev_list -> se_release_device_for_hba() list walk in core_delete_hba(), which is no longer required while using configfs VFS level parent/child struct config_group dependency referencing. The reason is because any struct se_hba->hba_dev_list-> struct se_device members are going to have to be released via: rmdir /sys/kernel/config/target/core/$HBA/* before rmdir release of struct se_hba via target_core_configfs.c: target_core_call_delhbafromtarget() -> core_delete_hba() rmdir /sys/kernel/config/target/core/$HBA to release struct se_hba in core_delete_hba(). This patch also removes the legacy se_clear_dev_ports() function, which is left-over pre-configfs shutdown logic for when se_free_virtual_device() was responsible for walking struct se_device->dev_sep_list and calling core_dev_del_lun() for each individual active struct se_port->se_lun. The reason this can be removed is because all struct se_device->dev_sep_list -> struct se_port communication is done via configfs symlinks, which means that an target fabric module's endpoints containg active struct se_port(s) will have to be released via target_core_fabric_configfs.c: target_fabric_port_unlink() via: unlink /sys/kernel/config/target/$FABRIC_MOD/$ENDPOINT/tpgt_$TPGT/lun/lun_$LUN_ID/<symlink> before rmdir release of struct se_device in target_core_configfs.c: target_core_drop_subdev() -> se_free_virtual_device() can happen via: rmdir /sys/kernel/config/target/core/$HBA/* to release struct se_subsystem_dev in target_core_drop_subdev() Reported-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Reported-by: Fubo Chen <fubo.chen@gmail.com> Signed-off-by: Nicholas A.
