in repository libguestfs.

commit 93f1bfcad74946824c6a12a456dbd01cee9a0571
Author: Richard W.M. Jones <rjones at redhat.com>
Date:   Tue Mar 11 14:40:38 2014 +0000

    Pass discard parameter from add-domain to add-drive.
    
    Allow callers to specify that all the disks from a domain are added
    with a specific discard mode (instead of always having discard
    disabled).
