That's cool but I think the proper solution is to write a Linux kernel module that can reserve GPU RAM via DRM to create ramdisks, not create a userspace filesystem using OpenCL.<p>That would give proper caching, direct mmap support if desired, a reliable, correct and concurrent filesystem (as opposed to this author's "all of the FUSE callbacks share a mutex to ensure that only one thread is mutating the file system at a time"), etc.
