    Add /proc/fs/nfsd/pool_stats to export to userspace various
    statistics about the operation of rpc server thread pools.
    
    This patch is based on a forward-ported version of
    knfsd-add-pool-thread-stats which has been shipping in the SGI
    "Enhanced NFS" product since 2006 and which was previously
    posted:
    
    http://article.gmane.org/gmane.linux.nfs/10375
    
    It has also been updated thus:
    
     * moved EXPORT_SYMBOL() to near the function it exports
     * made the new struct struct seq_operations const
     * used SEQ_START_TOKEN instead of ((void *)1)
     * merged fix from SGI PV 990526 "sunrpc: use dprintk instead of
       printk in svc_pool_stats_*()" by Harshula Jayasuriya.
     * merged fix from SGI PV 964001 "Crash reading pool_stats before
       nfsds are started".
