David sent me a mostly-working implementation for netfs and it does get rid of readpages, so it's just a matter of finding time for thorough tests and cleanups... I'd also like to let it sit in -next for a while (let's say at least one month), so realistically I need to look at it within the next few weeks and I honestly probably won't have time with my current schedule... But it'll definitely be done for 5.15 (next's next merge window), and probably in -next in ~2ish months if that's good enough for you. If you can convince me both cifs and nfs will get it done before then I might reconsider priorities :-D -- Dominique
