It's been that way for ages, how likely do you think that is? Not very, is my guess.

Well it's not my call, just seems like a really bad idea to change the error value. You can't claim full coverage for such testing anyway, it's one of those things that people will complain about two releases later saying it broke app foo. -- Jens Axboe - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
