This is needed in order to differentiate it from the value returned by the call. As a consequence, it enables revealing possible bugs in syscall parsers, for example, when the value read on syscall entering and not on syscall exiting, as it was the case with timerfd_settime parser. * tests/timer_xettime.c (main): Fill old.its field with value different from the expected one upon call return. * tests/timerfd_xettime.c: Likewise.
