29 * Largest number of bytes we need to allocate for an NFS
30 * call or reply. Used to control buffer sizes. We use
31 * the length of v3 WRITE, READDIR and READDIR replies
32 * which are an RPC header, up to 26 XDR units of reply
33 * data, and some page data.
35 * Note that accuracy here doesn't matter too much as the
36 * size is rounded up to a page size when allocating space.
