New Revision: 344656
URL: https://svnweb.freebsd.org/changeset/base/344656

Log:
  truss: Add support for fsync(2) and fdatasync(2).
  
  The default handling showed the argument as hex.  Add explicit handling so
  we can show it as decimal, since that's how we show file descriptors
  everywhere else.
