It's not a glibc problem really. The problem is this stupid error message in the kernel. We rely in many dozens of places on the kernel returning ENOSYS in case a syscall is not implemented and we deal with it appropriately. There is absolutely no justification to print these messages except perhaps in debug kernels. IMO the sys32_ni_syscall functions should just return ENOSYS unless you select a special debug kernel. One doesn't need the kernel to detect missing syscall implementations, strace can do this as well. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
