Assuming that syscalls may return negative values only as error codes, always print non-error syscall return codes as unsigned. * defs.h (RVAL_UDECIMAL): Remove. (RVAL_DECIMAL): Rename to RVAL_UDECIMAL. * syscall.c (syscall_exiting_trace) <case RVAL_DECIMAL>: Remove. * clone.c (SYS_FUNC(fork)): Remove RVAL_UDECIMAL. * lseek.c (SYS_FUNC(lseek)): Likewise. * prctl.c (SYS_FUNC(prctl)): Likewise. * uid.c (SYS_FUNC(getuid), SYS_FUNC(setfsuid)): Likewise. * times.c (SYS_FUNC(times)): Always return 0. * tests/inject-nf.c (main): Update expected output.
