The parts that I understand less are about how exactly the data from the device ends up in the right place in memory and how address_space and folios are built up for it. But these are precisely the parts that are not too relevant for a userspace driver. So, I would be very happy to work on a GPL FUSE driver for minix and get it to functional parity for all versions v1-v3. After that, and when all the available tests run well, we can start the deprecation process. I think this would be a great opportunity for me to learn and contribute something non-trivial, but that is still within my current level of ability. Shuah has also encouraged me to proceed on this track. However, since this is more than a couple of days work for me (for one I have to study the FUSE API), it would be helpful if I can get a sense of whether there is a reasonable chance for such work to be eventually included upstream. Of course, only IF it functions according to the criteria set out. I am not looking for guarantees, because I understand that is not how Linux development works, but just a sense of how the community feels about this. So far I have seen quite favorable responses, but I am too unfamiliar with the development process to understand how this may play out. Thanks again Jan and Jeff for your patient replies. Jori
