  Log:
  Increase the default socket buffer for NFS to deal with linux bugs and to
  improve performance.   The default nfs socket buffer is now 65535 bytes,
  settable with a sysctl (vfs.nfs.soreserve).
  
  It is my belief that when large data block sizes (32K) are negotiated,
  the larger socket buff should improve read-ahead performance and reduce
  nfs socket buffer lock contention that occurs with multiple nfsd's.  I
  was able to do some testing over GigE and it did seem to help, but problems
  with one of the machines made the tests less then reliable.
  
  Credits: Richard Sharpe originally encountered issues with linux NFS
  clients that were traced to linux doing a bad job in its delayed-ack code.
  David Rhodus created an initial patch which I used as a partial basis for
  this commit (circa October 2003).
