There is a lot, starting with core thread objects, sync objects etc.,
then there are skin-specific extensions of those and also objects that
are shared between processes. But even if you export all this, Xenomai
wasn't designed with this use case in mind. So you may find many tricky
corner cases around checkpoint/restart - just like in Linux...
What overall use case are you aiming at with CRIU for your RT
process(es)? What states would your processes be in when
saving/restoring? And what Xenomai version do you consider for this, 2.6
or upcoming 3.0?
