    umount - Remove sync() call from utility
    * Do not call sync() unconditionally when issuing the /sbin/umount command.
      Let the kernel take care of any syncing.
    * This may allow umount -f to operate better in situations where a mount
      might be stuck (such as a NFS mount), and also removes delays associated
      with scanning large numbers of vnodes on x86_64.
