Hi Mel-

I've been testing these four, which include a working version of
your bulk allocator patch. In "Refresh rq_pages" I've replaced
the cond_resched() call with schedule_timeout(), as you requested.

As always, review comments and test results are welcome.

      SUNRPC: Set rq_page_end differently
      SUNRPC: Refresh rq_pages using a bulk page allocator
      SUNRPC: Cache pages that were replaced during a read splice

      mm: alloc_pages_bulk()
