I concur with Daniel. If we can decide how to deal with that (toss one out, keep one, merge them, whatever), we could reuse all the user space glue that is the hardest part to get right. Current tip of development has some issues with conditional variables and broadcasts (requeue stuff) that I need to sink my teeth in. Joe Korty is fixing up a lot of corner cases I wasn't catching, but other than that is doing fine. How long ago since you saw it? I also implemented the futex redirection stuff we discussed some months ago. -- Inaky - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
