"WP" : "", I'm not keen on using "RELY" because I don't think it's at all obvious what it means. "RELI" would be closer, but still could use some improvement. Since we turned off this kernel output by default (at least on x86) because the line length had grown quite long, maybe we should just embrace it and print "RELIABLE" in full? -- Matt Fleming, Intel Open Source Technology Center -- 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/
