Subject: qemu: blockjob: Add reference to disk into struct qemuBlockJobData
X-Git-Url: http://xenbits.xensource.com/gitweb?a=commitdiff_plain;h=f877ec10209d6f5f0e8d48f3a8c50f74534f6a1b;p=libvirt.git

qemu: blockjob: Add reference to disk into struct qemuBlockJobData

Block jobs can also happen on objects which are not a disk at a given
point (e.g. the frontend was not hotplugged yet) and thus will be
eventually kept separately. Add a reference back to the disk for
blockjobs which do correspond to a disk.
