In nfs_dir_read() count used before and after limiting?

[Peter Dufault]

In nfs_dir_read() I see:

    /* align + round down the buffer */
    count &= ~ (DIRENT_HEADER_SIZE - 1);
    di->len = count;

Then later:
    if (count > NFS_MAXDATA)
        count = NFS_MAXDATA;

    di->readdirargs.count = count;

Can someone who understands this comment on it?
