One field is set but never access.
Another is accessed but never set.
Other are never mentioned at all.

Also remove the comment
	/* use separate field as it is set in interrupt to don't mess with
	 * protection of other bits using _bh lock
	 */

This is not correct - were it used, obd_recovery_expired would be part
of the same 'unsigned long' as the other fields.
