This has nothing to do with PIDs. We need 64-bit values for more complex bit fields which can then be stored in the futex. One example is a new, much faster rwlock implementation. These are not practical without 64-bit futexes. This is why I asked Ingo to add the code. -- ➧ Ulrich Drepper ➧ Red Hat, Inc. ➧ 444 Castro St ➧ Mountain View, CA ❖
