函数名称：debug_object_assert_init - debug checks when object should be init-ed*@addr: address of the object*@descr: pointer to an object specific debug description structure

函数原型：void debug_object_assert_init(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
847  如果非debug_objects_enabled则返回
850  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.
852  raw_spin_lock_irqsave( & lock, flags)
854  obj等于Lookup an object in the hash bucket.
855  如果非obj则
856  struct debug_obj o = {object = addr, state = ODEBUG_STATE_NOTAVAILABLE, descr = descr}
860  raw_spin_unlock_irqrestore( & lock, flags)
866  如果is_static_object且is_static_object(addr)则
868  debug_object_init - debug checks when an object is initialized*@addr: address of the object*@descr: pointer to an object specific debug description structure
869  否则
870  debug_print_object( & o, "assert_init")
871  Try to repair the damage, so we have a better chance to get useful* debug output.
874  返回
877  raw_spin_unlock_irqrestore( & lock, flags)
