The information about forced livepatch transition is currently stored
in struct klp_patch. But there is not any obvious safe way how to
access it when the split livepatch modules are removed.


If that's the only motivation to do this, klp_objects could have a reference to the klp_patch they are part of. This could easily be set when adding the klp_object to the klp_patch->obj_list in klp_init_object_early() .

Having this reference could also prove useful in future scenarios.

Cheers,
