In particular fsys_getppid always returns the ppid in the initial pid namespace so it does not work for a process in a pid namespace. Fix from Eric Biederman just removes the fast system call path. While it is a little bit sad to see another one of these bite the dust ... I can't imagine that getppid() is really on any real applications critical path.
