Name:Scan a memory block corresponding to a kmemleak_object. A condition is* that object->use_count >= 1.

Proto:static void scan_object(struct kmemleak_object *object)

Type:void

Parameter:

TypeParameterName

1330  If Not (bject status flags & lag representing the memory block allocation status ) Then Go to out
1333  If hlist_empty( & memory ranges to be scanned inside an object (empty for all) ) || bject status flags & lag set to fully scan the object when scan_area allocation failed Then

1341  Scan a memory block (exclusive range) for valid pointers and add those* found to the gray list.

Caller
NameDescribe
scan_gray_listScan the objects already referenced (gray objects). More objects will be* referenced and, if there are no memory leaks, all the objects are scanned.
