类型参数名称
struct kobject *kobj
614  如果非kobj则返回
617  sd等于 sysfs directory entry
618  ktype等于get_ktype(kobj)
620  如果ktype则sysfs_remove_groups(kobj, default_groups)
623  sysfs_remove_dir(kobj)
624  sysfs_put(sd)
626  state_in_sysfs等于0
627  move the kobject from its kset's list
628  递减引用计数对象

blk_register_queuelk_register_queue - register a block layer queue with sysfs*@disk: Disk of which the request queue should be registered with sysfs.
blk_unregister_queuelk_unregister_queue - counterpart of blk_register_queue()*@disk: Disk of which the request queue should be unregistered from sysfs.* Note: the caller is responsible for guaranteeing that this function is called* after blk_register_queue() has finished.

blk_integrity_del
__threshold_add_blocks
elv_unregister_queuelv_unregister_queue is called from either blk_unregister_queue or* elevator_switch, elevator switch is prevented from being happen* in the two paths, so it is safe to not hold q->sysfs_lock.
