It's not done recursively, though. checkpoint_write_userns() will only be called by checkpoint_write_user(). checkpoint_write_user() will make sure there are only 5 levels deep of unwritten creator user namespace (else bail), then start at the oldest creator, and write it. That checkpoint_write_user will cause a write of its user_ns, then write the user, then return to the original checkpoint_write_user() which will now write the next-oldest user_struct So the max recursion depth we get is: checkpoint_task_struct -> checkpoint_write_cred -> checkpoint_write_user -> checkpoint_write_user -> checkpoint_write_userns (END) -serge _______________________________________________ Containers mailing list Containers@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/containers
