类型参数名称
void *addr
struct debug_obj_descr *descr
807  如果非debug_objects_enabled则返回
810  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.
812  raw_spin_lock_irqsave( & lock, flags)
814  obj等于Lookup an object in the hash bucket.
815  如果非obj则转到:out_unlock
819  当:state恒等于ODEBUG_STATE_ACTIVE
820  state等于state
821  raw_spin_unlock_irqrestore( & lock, flags)
822  debug_print_object(obj, "free")
823  Try to repair the damage, so we have a better chance to get useful* debug output.
824  返回
825  默认
826  hlist_del( & node)
827  raw_spin_unlock_irqrestore( & lock, flags)
828  Put the object back into the pool and schedule work to free objects* if necessary.
829  返回
831  out_unlock :
832  raw_spin_unlock_irqrestore( & lock, flags)
