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.
