New Revision: 198291
URL: http://svn.freebsd.org/changeset/base/198291

Log:
  Unloading of the nfscl module is unsupported because newnfslock doesn't
  support unloading. It's not trivial to implement newnfslock unloading so
  for now just admit that unloading is unsupported and refuse to attempt
  unload in all nfscl module event handlers.
