you misunderstand me. I have a working solution, using fuse. if he thinks that's bad, it's on him to provide a correct in-kernel solution, then show me it's faster
Read the whole thread (or even just the immediate parent email, from Andrew Morton). Linus wasn't saying "don't use fuse for this", he was pushing back against a suggestion that the existence of the fuse implementation was a reason not to merge a kernel implementation.
