Full-blown gemfs does not come in here, of course; but let me fire a warning shot since you mention it: if it's going to use swap, then we shall probably have to nak it in favour of continuing to use infrastructure from mm/shmem.c. I very much understand why you would love to avoid that dependence, but I doubt it can be safely bypassed.
