Hello,
I am investigating an issue with deleting snapshot in oVirt 4.3.10. Basically the delete
snapshot operation fails and I am seeing following error in VDSM(vdsm-4.30.46) log -

I found out that there is an issue logged here
https://bugzilla.redhat.com/show_bug.cgi?id=1785939. However I am not able to see how it
was fixed and whether it was merged in oVirt. Where can I find the relevant commit (in
vdsm and/or libvirt)?
Thanks
