If we knew we were going to stop here, I wouldn't mind "volatile". I too like the fact that the user config means something functional. But if we are considering to expand it later to sync=fs and maybe sync=writeback, then it is going to be quite hard to come by with equally meaningful names and the "sync=" modes would end up being less confusing IMO. So I cast my vote for "sync=off". We could also make "volatile" an alias to "sync=off" if it makes anyone happier. Thanks, Amir.
