However, at the VM and/or vm/fs things we had, I was happy enough for this thing of Christoph's to get merged. Actually I even didn't care if it had mmap support, so long as it solved their problem. But a solution to the general problem of VM and IO scalability, it is not. IMO. > And the fact is, nobody but SGI customers would ever want the 16kB > blocksize. IOW - NONE OF THIS MATTERS! Maybe.
