특별히 셋팅하지 않는 이상 sync()와 remount_ro()를 수행한뒤 리부팅을 한다.

int android_reboot(int cmd, int flags, char *arg)
{
    int ret;

    if (!(flags & ANDROID_RB_FLAG_NO_SYNC))
        sync();

    if (!(flags & ANDROID_RB_FLAG_NO_REMOUNT_RO))
        remount_ro();

    switch (cmd) {
        case ANDROID_RB_RESTART:
            ret = reboot(RB_AUTOBOOT);
            break;

        case ANDROID_RB_POWEROFF:
            ret = reboot(RB_POWER_OFF);
            break;

        case ANDROID_RB_RESTART2:
            ret = __reboot(LINUX_REBOOT_MAGIC1, LINUX_REBOOT_MAGIC2,
                           LINUX_REBOOT_CMD_RESTART2, arg);
            break;

        default:
            ret = -1;
    }

    return ret;
}
