函数原型：void debug_object_destroy(void *addr, struct debug_obj_descr *descr)

返回类型：void

参数：

类型参数名称
void *addr
struct debug_obj_descr *descr
756  bool print_object = false
758  如果非debug_objects_enabled则返回
761  db等于We use the pfn of the address for the hash. That way we can check* for freed objects simply by checking the affected bucket.
763  raw_spin_lock_irqsave( & lock, flags)
765  obj等于Lookup an object in the hash bucket.
766  如果非obj则转到:out_unlock
770  当:state恒等于ODEBUG_STATE_NONE
771  当:state恒等于ODEBUG_STATE_INIT
772  当:state恒等于ODEBUG_STATE_INACTIVE
773  state等于ODEBUG_STATE_DESTROYED
774  退出
775  当:state恒等于ODEBUG_STATE_ACTIVE
776  state等于state
777  raw_spin_unlock_irqrestore( & lock, flags)
778  debug_print_object(obj, "destroy")
779  Try to repair the damage, so we have a better chance to get useful* debug output.
780  返回
782  当:state恒等于ODEBUG_STATE_DESTROYED
783  print_object = true
784  退出
785  默认
786  退出
788  out_unlock :
789  raw_spin_unlock_irqrestore( & lock, flags)
790  如果print_object则debug_print_object(obj, "destroy")
