So to get this straight - you want to add a new pointer to task_struct for each possible virtualized entity?
After you're doing by how many bytes will task_struct be bloated? I don't think that's a very good approach because you'll crank up the per thread memory overhead which is already far too big in Linux. Also it adds cache foot print and generally makes things slower.
If anything I would request using a proxy data structure that contains all the virtualized namespaces for a set of processes. And give each task only has a single pointer to one of these.
