      This task is going to address the problem of poor small IO write performance in Lustre.

      We only talk about cached I/O here because LU-4198 has a decent solution to improve AIO + DIO for small I/O.

      Also for the workload of small I/O, it assumes the pattern of I/O is highly predicated. In another word, it won't help the workload of small random I/O.

      The small I/O doesn't have to be page aligned.
