init/Kconfig:

        config PRINTK_EXT_LOG
                bool

drivers/net/Kconfig:

        config NETCONSOLE
                tristate "Network console logging support"
                select PRINTK_EXT_LOG

kernel/printk/printk.c:

        void console_unlock(void)
        {
#ifdef CONFIG_PRINTK_EXT_LOG
                static char ext_text[CONSOLE_EXT_LOG_MAX];
#endif

etc.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
