<div>On addition of first path, reservation_key parameter is not selected before</div>
<div>handling persistent reservations. This leads multipathd to not perform</div>
<div>registration on the path even when registrations exist on the LUN.</div>
<div><br>
</div>
<div>Added code to select "reservation_key" parameter value before calling</div>
<div>PR handler during addition of new path to a new map.</div>
