The support of async disk I/O in Linux differs depending on kernel version and file system type. But it is possible to get 100% async I/O with the is_submit(), and dqlite will leverage that if detected.

There is now a new async I/O API available in Linux (I'm not remembering the name right now, but it was developed by folks at Facebook). It looks promising so I'll check it at some point. (dqlite author here)
