    sys/ufs/ufs          ufs_vnops.c 
  Log:
  In ufs_chmod(), use privilege only when required in the following
  cases:
  
  - Setting sticky bit on non-directory
  - Setting setgid on a file with a group that isn't in the effective
    or extended groups of the authorizing credential
  
  I.e., test the requirement first, then do the privilege test,
  rather than doing the privilege test regardless of the need for
  privilege.
