    I understand that. I can, however, round up the netfs I/O granule size and
    alignment to a multiple of the cachefile I/O block size. Also, I'm doing DIO,
    so I have to use block size multiples.

    But if the filesystem can avoid bridging large, appropriately sized and
    aligned blocks, then I can use it.
