Steven's suggestion seems more sensible. sed 's/CONFIG_PRINTK_NMI/CONFIG_PRINTK_NMI_BACKTRACE/g' sed 's/printk_nmi/printk_nmib/g' or sed 's/printk_nmi/nmi_backtrace/g' might work well. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
