But at the same time I'd like to avoid sync becoming serialised on its writes. If you've got a lot of filesystems mounted, doing each filesystem's sync sequentially and synchronously is going to be a lot slower than allowing async syncs. In other words, for sync(2) we really want async commit submission followed by a synchronous wait for completion. And that's probably more churn than I'd like to see at this stage for 2.4.
