130 * Requests are copied into these pages as they arrive. Remaining
131 * pages are available to write the reply into.
132 *
133 * Pages are sent using ->sendpage so each server thread needs to
134 * allocate more to replace those used in sending. To help keep track
135 * of these pages we have a receive list where all pages initialy live,
136 * and a send list where pages are moved to when there are to be part

138 *
139 * We use xdr_buf for holding responses as it fits well with NFS
140 * read responses (that have a header, and some data pages, and possibly
141 * a tail) and means we can share some client side routines.
142 *
143 * The xdr_buf.head kvec always points to the first page in the rq_*pages
144 * list. The xdr_buf.pages pointer points to the second page on that
145 * list. xdr_buf.tail points to the end of the first page.
146 * This assumes that the non-page part of an rpc reply will fit
147 * in a page - NFSd ensures this. lockd also has no trouble.

149 * Each request/reply pair can have at most one "payload", plus two pages,
