New Revision: 53946
URL: https://svnweb.freebsd.org/changeset/doc/53946

Log:
  Make it absolutely clear that the operator group grants access privileges
  that might not be immediately obvious.
  
  Also catching up on a bit of documentation to reflect that GELI has been
  passing TRIM/UNMAP requests since 2015.
