probably. I see that this implementation is in kernel since import to git...

What's the right solution in this particular case?
It is exactly the same situation (using embedded kobj like module handle does).

In DM, the whole problem here is that kobject is used for attribute representation
of mapped device, mapped device struct is using its own reference counting
and can dissappear before the kobject. So it must properly solve this situation.

Sure, working on it. Proper fix will replace this when ready.
