    Description

      Readahead always try to align readahead with RPC size, but this
      could introduce a problem if readahead window is smaller than RPC size.

      With current codes, it will fallback a lot of 4k read because most of readahead stop, fix this to align with readahead window rather than RPC size in this case.
