드라이버 외부의 다른 부분에는 영향을 주지 않으므로 그런 변경은

If you say Y here, some extra kobject debugging messages will be sent

+ kobjects are reference counted objects. This means that their
+ last reference count put is not predictable, and the kobject can
+ live on past the point at which a driver decides to drop it's
+ initial reference to the kobject gained on allocation. An
+ example of this would be a struct device which has just been
+ unregistered.
+
+ However, some buggy drivers assume that after such an operation,
+ the memory backing the kobject can be immediately freed. This
+ goes completely against the principles of a refcounted object.
+
+ If you say Y here, the kernel will delay the release of kobjects
+ on the last reference count to improve the visibility of this
+ kind of kobject release bug.
