Lol.  Do you understand what container_of does?
This is not dynamic_cast<> with RTTI.

You can put any type name in there that you like,
so long as it has a field name to match.  The type
of the field you give doesn't even have to match
the type of the pointer that you pass in.

Type safety this is not.
