However, that's three or four months away. The current code is merely a stopgap for now.=20 Many folks have an interest in having a cluster filesystem in mainline. This seems like an issue that can be resolved later, not a big blocker. That is, it would be worth more to people to have it in mainline for the next four months, knowing this will get fixed, than keeping it out of mainline for four months over this feature. > - the buffered aio mess needs sorting out. imho the best thing was Well, that's a mainline problem. Yes, we should all work towards improving mainline.

There are some sizeable things on this "top of the head" list already. I'd like to find a nice balance between "goes to mainline now" and "must be a perfect piece of software before it goes in." No software will ever be perfect.
