New Revision: 210268
URL: http://svn.freebsd.org/changeset/base/210268

Log:
  For the experimental NFSv4 server's dumplocks operation, add the
  MPSAFE flag to cn_flags so that it doesn't panic. The panics weren't
  seen since nfsdumpstate(8) is broken for the "-l" case, so this
  was never done. I'll do a separate commit to fix nfsdumpstate(8).
