Proposal for adding O_DIRECT support into JDK 9

[Brian Burkhalter]

Hi Lucy,

Here is a slightly reworded version of your draft.

Thanks,

Brian

    /**
     * File storage is typically organized into discrete sequences of bytes called
     * <i>blocks</i>. A block is the smallest storage unit of a file store. Each read
     * and write operation is performed on a multiple of blocks.
     *
     * @implSpec The implementation in this class throws an
     *         {@code UnsupportedOperationException}.
     *
     * @return  the block size of this file store, in bytes
     *
     * @throws  IOException
     *          if an I/O error occurs
     *
     * @throws  UnsupportedOperationException
     *          if the operation is not supported
     *
     * @since 10
     */
