We used to have an implementation which tried to hold onto the task_struct and that sucked. It is only possible for the task to disappear without notifying devio under very special conditions only, which involve forking with parent exiting. In other words, even a buggy application won't trigger this without deliberately trying. And when it happens, uid checks make sure that other users are not affected. > Holding a reference > to a struct pid avoid that problem, and paves the way > for implementing a pid namespace.
