I'll work on that. It's a lot easier to have a packaged set of tests that say yes/no, though, and it's handy when those tests are fully open-source and easy to run (DOSEMU, in contrast, requires the annoyingly impossible-to-compile freedos stuff iirc, and the interesting bits need other test programs). In any case, I'll add a self-test for the err thing once I figure out what's going on. --Andy -- Andy Lutomirski AMA Capital Management, LLC -- 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/
