>Description:
I have been relying on fstat to verify that files are closed before processing in batch FreeBSD 5.3-RELEASE and parsing the output.  6.0-RELEASE does not report open files in the same manner.

>How-To-Repeat:
5.3-RELEASE:
  ;cd /var/log
  ;fstat messages
USER     CMD          PID   FD MOUNT      INUM MODE         SZ|DV R/W NAME
root     syslogd      296    9 /var      16486 -rw-r--r--   79798  w  messages


6.0-RELEASE:
  ;cd /var/log
  fstat messages
USER     CMD          PID   FD MOUNT      INUM MODE         SZ|DV R/W NAME
(no output)
