No, staging is for gettingn code into, or out of, the kernel tree, not for anything else. I have allowed it to be used to hold drivers in that are not "acceptable", while another driver was written by others from scratch to work properly on that hardware, and then the original one is dropped. That's ok, as there is a time-limit on how long the code lives in the staging tree. But to try to use it to create a multi-os solution, no, that's not what staging is for. Also, please review the past multi-os driver initiatives that have sprung up over the years (about 1 every 10 years it seems). Please learn from the past as to why those have failed every single time, and why we don't want to even try to do that again. thanks, greg k-h -- 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/
