It is also worth noting, that we have a unique number for all kinds of custom protobuf options(see [[Images#Notes_about_protobuf]]), so you don't have to worry that it might collide with others.

In kernel there's no API that can just reveal the tasks-to-objects map. Instead, there's an API called <code>kcmp()</code> that compares two e.g. file descriptors and reports back whether the file referenced by them is the same or not. In CRIU we have a [https://github.com/xemul/criu/blob/master/kcmp-ids.c KCMPIDS] engine that uses this API, build [[kcmp trees]] and turns the equals-notequals answers into a list of IDs of objects.
