New Revision: 252067
URL: http://svnweb.freebsd.org/changeset/base/252067

Log:
  Since some NFSv4 servers enforce the requirement for a reserved port#,
  enable use of the (no)resvport mount option for NFSv4. I had thought
  that the RFC required that non-reserved port #s be allowed, but I couldn't
  find it in the RFC.
