    identify multipage ->writepages() calls · 22905f77

     NFS needs to be able to distinguish between single-page ->writepage() calls and
     multipage ->writepages() calls.
    
     For the single-page writepage calls NFS can kick off the I/O within the
     context of ->writepage().
    
     For multipage ->writepages calls, nfs_writepage() will leave the I/O pending
     and nfs_writepages() will kick off the I/O when it all has been queued up
     within NFS.
