In userspace, I perform such operation:

ret = write(fd, access_address + 2, sizeof(long));... you know that accessing this at unaligned offsets isn't going to work. It's completely meaningless. Why are you trying to do it? _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
