On further reflection, this probably would be safe after all. Since we don't call put_container_group() in attach_task() until after synchronize_rcu() completes, that implies that a container_group_get() from the RCU section would have already completed. So we should be fine. Paul ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
