Hello, I have a simple question. If a parent maps a page into a child's space with this flag, can the parent regain this page and remove this mapping later? I did a simple test. It seems that with this flag in l4_task_map, the child owns the mapped page permanently. What I'd like to do is when a child finishes its job and returns such a granted page to its parent, the parent can reuse this page for some other child. Thanks. _______________________________________________ l4-hackers mailing list [email protected] http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers
