[Users] Snapshot delele/merge broken. Was: Live storage migration snapshot removal (fails)

[Sander Grendelman]

Snapshot deletion on preallocated FC domain disks is broken in ovirt-stable/3.3

Both online and offline snapshot deletion leads to an error and the
snapshot state is changed to "BROKEN".

When I apply the patch at http://gerrit.ovirt.org/#/c/19983/ from
https://bugzilla.redhat.com/show_bug.cgi?id=1015071 snapshot deletion
works again.

Can/will this patch be backported to ovirt-stable?
